1.Balancing hammers for machinery;
racing weight blocks.
2. Mobile phone and game machine vibrators;
The advantages of tungsten alloy counterweight block are mainly as follows:
1. Environmentally friendly, less polluting to the production environment
2. Higher density, easier to control the weight distribution and smaller volume of the prepared counterweight block.
3. High corrosion resistance and long service life.
