General overview
The thick alloy of this product has very strong hardness and strength properties. ALUMOLD 600 is mainly used for injection molding abrasives and large loading tools. Its high strength and hardness characteristics have excellent wear resistance and non-breakdown!
Processing process
Solderability
Repair welding
Splicing welding is not suitable
Good machinability
Since the ALUMOLD 600 plate passes through the stretching process, there is no subsequent heat treatment;
Corrosion characteristics
Suitable for inland and marine climate conditions;
Surface treatment performance
Anodizing
Decorative, not suitable
Polishing performance
Plating Luo is very suitable
Electroless nickel plating
Chemical texture is very suitable
