Will win. The winner is metal-ceramic hard alloy. A hard alloy of tungsten carbide WC and cobalt in a ratio of 90% and 10% by weight, respectively. It is close to diamond in hardness and is used when drilling rocks. Developed in 1929 in the USSR where it was mainly used for cutting tools. Now the alloy is used to equip drawing tools, as cutters, etc. When creating, powder metallurgy methods are used. Metal-ceramic alloys have particularly high hardness. Pobedit is made in the form of plates of various shapes and sizes. The manufacturing process is as follows: fine powder of tungsten carbide or other refractory carbide and fine powder of cobalt or nickel binder metal are mixed and then pressed into appropriate shapes. The pressed plates are sintered at a temperature close to the melting point of the binder metal, resulting in a very dense and hard alloy. Plates made from this superhard alloy are used for the manufacture of metal-cutting and drilling tools. The plates are soldered onto the cutting tool holders with copper. No heat treatment required. Currently, other tungsten-cobalt alloys have been developed, but the name “win” continues to be used for them.

It is unlikely that in the modern world there is at least one man with “straight arms” who has never used, or at least not heard of, the so-called Pobedit drills. In fact, in such drills only the tip is coated with a special material called pobedit. Let's take a closer look at this material.

Wins - composition and properties

It appeared in the USSR back in 1929. The material is a hard metal alloy. The composition of Pobedite includes tungsten carbide and cobalt, the mass ratio of which is 90:10.

Pobedit is characterized by high strength, wear resistance and hardness. However, products made from Pobedite exhibit such disadvantages as causticity and fragility upon impact, so in practice Pobedite spraying and the use of cutting and drilling tool tips are used. Thanks to the tips and spraying, the tool is given properties that significantly increase wear resistance to abrasion and dullness.

Manufacturing method

The alloy is produced in industry not by casting, like cast iron and copper alloys, but by sintering a pressed mixture of composite powder. A ceramic-metal composite alloy is created by mixing fine tungsten carbide powder and cobalt as a binder. The resulting fine powder mixture is placed in special molds in the form of plates of various shapes and sizes and sintered. Due to the high sintering temperature, which is close to the melting point of the binder material, the result is a unique material with high strength and hardness.

Unlike classical technology, the main components of the alloy can be replaced with other analogues, for example, nickel can act as a binder. However, in practice these alloys are also usually called pobedit.

Scope of application

It is practically indispensable in the mining industry, where it is used as a spray coating for drilling parts of hard rock drilling equipment. In metalworking, pobedit coatings and tips are used in metal-cutting equipment and drawing tools. Pobeda also finds its application in woodworking. Pobedit's high hardness and heat resistance effectively protects equipment used in difficult conditions, giving it good wear resistance characteristics.

At the domestic level and in construction, drills for rotary hammers and impact drills are used for drilling concrete walls.

I read somewhere that initially it was an alloy that was called victorious, a cast alloy, like quick-cutting alloys, but with a large amount of carbon and tungsten, so that the carbide content reached 80%. They made it in 1929 as a domestic analogue of stellites. and after the war, in connection with the development of powder metallurgy methods, the powder alloy VK10 began to be called victorious. I came across drills made of carbide alloy, size 5; 6:7: mm length about 6-7 cm, it was about 4 years ago at some exhibition it cost about 300 rubles

With us you can profitably sell scrap VK TK (wins), scrap hard alloys at competitive prices.

The winner is a hard alloy of tungsten carbide and cobalt in a mass ratio of 90:10. The presence of these metals in the composition also explains the high cost at which the VK TK can be handed over. Possessing high hardness, pobedit is used in rock drilling, metalworking (for equipping drawing tools, as cutters, etc.), woodworking and as critical parts that require high hardness or heat resistance.

Developments in industrial sintering of tungsten carbide were carried out in Germany in the 1920s. In 1929, Pobedit became the first such alloy produced in the USSR, where it was mainly used for cutting tools. When creating, powder metallurgy methods are used.

VeCo LLC provides the highest prices per kg of VKTk alloy (win)

Metal-ceramic composite alloys have particularly high hardness. Pobedit is made in the form of plates of various shapes and sizes. The manufacturing process is as follows: fine powder of tungsten carbide or other refractory carbide and fine powder of cobalt or nickel binder metal are mixed and then pressed into appropriate shapes. The pressed plates are sintered at a temperature close to the melting point of the binder metal, which produces a very dense and hard material. Carbide inserts are used for the manufacture of metal-cutting and drilling tools: they are soldered onto the cutting tool holders with copper. No heat treatment required.

Currently, other tungsten-cobalt composite alloys have been developed, but the name “win” continues to be used for them.

It is also worth noting that tungsten and cobalt alloys are not always used exclusively in peaceful industrial production. Another area of ​​application is, for example, the production of armor-piercing cores for projectiles and bullets.

We buy Pobedit scrap in any quantity. Both industrial enterprises and small firms and individuals can submit the winnings. Reception is carried out by specialists who can competently and honestly evaluate scrap, including tungsten-cobalt alloys. In addition, VeCo LLC will help you remove a large shipment from your territory

Selling VK Tk at a high price is real. Our company has all the qualities for this, and the presence of a Niton analyzer will show in seconds the chemical composition of any alloy, since the price of Vk Tk is very dependent on the chemical purity of the material. We can buy VK TK at a high price in Moscow and the region.

Pobedit belongs to the so-called group of hard alloys. These are hard and wear-resistant ceramic-metal alloys formed on the basis of highly hard and refractory materials bound with a cobalt or nickel binder. Scrap hard alloys are always highly valued at metal and alloy collection points.

Hard alloys can be divided into the following groups:

Tungsten-cobalt hard alloys (VK);

Titanium-tungsten-cobalt hard alloys (TK);

Titanium-tantalum-tungsten-cobalt hard alloys (TTK)

We will buy scrap VK TK. The price is high!

Hard alloys divided into cast and sintered. Cast hard alloys are usually used for surfacing on working tools. Sintered hard alloys produced by powder metallurgy methods are amenable only to grinding or methods of physical and chemical action. Recently, the production of hard alloy plates using the sintering method used for a variety of metal processing processes has become widespread.

Hard alloys find their application in the following areas:

Branding

Drawing

Stamping

Processing of materials by cutting: cutters, drills, milling cutters, carbide inserts

Mining and ore mining equipment

Bearing production

We will buy hard alloy at a favorable price for you.

Vk8, Vk10, Vk15, Vk20

In the group of tungsten-cobalt alloys, the most common grades are Vk6, Vk8, Vk10, Vk15, Vk20, where the numbers indicate the percentage of cobalt. VK hard alloys are used for processing materials by cutting, semi-finish milling of solid surfaces, for equipping mining tools, for chip-free processing of metals, wear parts of machines, instruments and fixtures: drawing, calibrating and pressing rods and pipes made of steel, non-ferrous metals and their alloys. In this group, the most widely used alloy is VK8, used in the mining industry and mechanical engineering. Based on it, the VP3325 brand is also produced, characterized by increased wear resistance, impact strength, and vibration resistance.

We accept VK8 hard alloy scrap in the form of:

Vk8 cutter

VK8 plate

Drill VK8

VK8 cutters

T30K4,T15K6,T5K10

In the group of titanium-tungsten-cobalt alloys, the most common grades are T30K4, T15K6, T5K10. Here, after the letter T, the percentage of titanium carbide is indicated, and after K, the percentage of silicon. TK alloys are used for processing materials by cutting: fine turning with a small cut section (such as diamond cutting); thread cutting and reaming of unhardened and hardened carbon steels. Scrap of this group of alloys is found in the form of:

T30K4 cutter, T15K6, T5K10 cutter

T15K6 plates, T5K10 plates

T5K10 cutters

A hard alloy, the price of which, due to the metals included in its composition, always remains high, is very often found at collection points for various scrap materials. However, few firms can provide fair reception. VeCo LLC can accurately determine the composition of any scrap, and therefore ensure fair acceptance. We will buy hard alloy at a price corresponding to the current state of the metal market.
