MCP Hardener Alloys
The hardening of aluminium alloys by inclusion of small additions of bismuth and lead is rapidly increasing. To enable such additions to be made easily and accurately Mining & Chemical Products Ltd. produce MCP Hardener Alloys which are controlled mixtures of bismuth and lead cast in the form of thin sticks weighting 1 lb. which may be thrown into the melt to provide exactly the addition required.
