HIGH COPPER ALLOY
AMPCOLOY® 89 FORGED
AMPCOLOY® 89 is generally deployed in similar applications AMPCOLOY® 95. Although both alloys are identically classified, AMPCOLOY® 89 is differentiated by its slightly higher mechanical properties.
AMPCOLOY® 89 is principally used for flash welding dies, welding wheels, electrodes for mesh welding, damper ring segments and damper rings for generators and parts for injection molding of plastic.
Since the alloy contains 0.4% Beryllium, it is recommended that during any operation which is liable to create dust or fumes (for example dry grinding, polishing or welding) precautions should be taken to ensure there is no inhalation or exposure to eyes or skin. Conventional machining (for example milling and turning) is not generally considered hazardous.
