Aluminum Bronze – Plastic Injection Molding Dies for Mold Construction
Benefits
- High tensile and fatigue strength
- Extreme toughness, even at high temperatures up to 400°C
- Thermal conductivity increases as temperature increases
- Excellent resistance to scaling, erosion, and cavitation pitting
- Excellent corrosion resistance, especially in environments with high humidity
- Easy mechanical processing
- Good sliding properties
- Can be used in the delivered condition, no hardening required, thus no warping like with steel
- MIG and TIG welding possible
- Reduced cycle times and production costs by eliminating costly coolant duct systems
