Weight Counterweight PM Sintered Parts

At present, the manufacturing process of weight tungsten alloy counterweight is mainly divided into lost wax precision casting process, forging process, and powder metallurgical process. Generally speaking, the cost of the precision de-staggered casting process is relatively low, but the rod head component still needs more functional and appearance modification processing after casting. The forging process has many advantages, as well as high accuracy and stability.

Advantages of tungsten alloy weight counterweight

1. High density (16.5g/cc~18.6g/cc)

2. High tensile strength, high toughness, high hardness, and good mechanical properties

3. Corrosion resistance

4. Good compactness

5. Consistent color

6. Small size

It can be said that tungsten alloy is the material of choice for weight counterweights. Tungsten alloy Weight counterweight PM sintered parts counterweights have excellent properties. Because of the unique properties of tungsten alloys, tungsten alloy weight counterweights are especially suitable for various types of weights. Tungsten alloys are twice as dense as steel and much higher than aluminum. Can be customized.
