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

 

Stock/Quality

  • We saw to your desired dimensions – fast, clean, and true to size!
  • sheets with polished surfaces starting at 4 mm thickness, with milled surfaces from 27 mm to 145 mm thickness
  • Pressed bars with edges, straightened: flat from 20x10mm to 160x52mm, square from 20x20mm to 90x90mm
  • 100% ultrasonically tested
  • Thermally relaxed
  • Flatness max. 3 mm/m
