Product Description
1) Specific gravity: Generally, the specific gravity is 16.5-18.75g/cm3;
2) High strength: tensile strength 700-1000Mpa;
3) Strong radiation absorption ability: 30-40% higher than lead;
4) Large thermal conductivity: The thermal conductivity of tungsten alloy is 5 times that of mold steel;
5) Small thermal expansion coefficient: only 1/2-1/3 of steel;
6) Good electrical conductivity; Due to its good electrical conductivity, it is widely used in lighting and welding industries;
7) It has good weldability and processability.
High specific gravity tungsten alloy is vividly called 3-high (or 3H) alloy, that is: high-density, high-strength, high-hardness alloy. Therefore, an important use of high specific gravity alloys is in widely used counterweight components.

Military series: armor-piercing bullets; submunitions, balls, rods, square particles, cylinders, other tungsten alloy electric head blocks, tungsten alloys for nuclear technology applications.
Process flow
1. Mixing: Mix tungsten powder, nickel powder and iron powder (if the product has magnetic requirements, copper powder can be added instead of iron powder).
Mixing → Vacuum drying → Press molding → Pre-burning and degreasing → Processing and molding → Vacuum sintering → Quality inspection → Blank products → Subsequent processing (oil immersion, machining, heat treatment, electroplating, rolling, forging, etc.) → Precision grinding products → Products out of warehouse
Reasons for choosing tungsten alloy counterweights
1. High specific gravity: Adding tungsten alloy counterweights to the car can maintain the high performance of the car during operation and provide a certain degree of controllability for the car.
2. High tensile strength and hardness: Because tungsten alloy has high tensile strength and hardness, it can be used in limited spaces, such as inside racing cars.
3. Easy to process: Because tungsten alloy is easy to process, it provides designers with greater design space.
Tungsten alloy counterweights are non-toxic and environmentally friendly, replacing toxic and environmentally harmful products. At the same time, they are lighter than traditional ones, weighing twice as much as lead, and retain their shape for a long time. It can also be used to produce other parts of fishing gear, such as tungsten alloy wire cutting.
