AMPCO METAL AMPCOLOY® 940 Nickel-Copper, Extrusion, 25 - 50 mm.

 

Subcategory: Copper Alloy; Nickel Alloy; Nonferrous Metal

Close Analogs:

Composition Notes: Copper content calculated from balance.

Key Words: RWMA Class 3

Material Notes:
AMPCOLOY 940 is a patented alloy which meets the demands of users of the RWMA class 3 alloys without Beryllium. In the industrialized countries, stricter health and safety instructions on the use of noxious elements have forced AMPCO to develop this new alloy. It replaces the AMPCOLOY 95 in practically all applications.

Applications: AMPCOLOY 940 is used wherever a good electrical or thermal conductivity is required together with high mechanical properties: Electrode holders and seam welding shafts; Spot welding electrodes, seam welding discs, projection and butt welding dies, principally for stainless steel and Monel; Plunger tips for cold chamber aluminum die casting machines; Parts of moulds for injection moulding of plastics, injection-nozzles and cooling pins; Brake drums for paper winding rolls; Parts for energy engineering
