Properties and Specifications



AMPCOLOY® 89 is a remarkable bronze alloy that has been forged and extruded to achieve optimum physical properties. Designed with slightly higher electrical and heat transfer properties than AMPCOLOY® 95, it offers exceptional wear and corrosion resistance. This unique composition results in superior thermal conductivity, improved cycle time, and longer tool life – up to 50% longer than copper-titanium. With its high tensile strength, AMPCOLOY® 89 is the ideal choice for applications requiring durability and efficient heat transfer.

Applications



AMPCOLOY® 89 has a wide range of applications in various industries. Its exceptional electrical and heat transfer properties make it a preferred choice for flash welding tools, welding wheels, and mesh welding electrodes. It also excels as a plunger tip in aluminum die casting machines and as a component in molds for plastic injection molding. Whether producing precision components or enhancing the performance of welding equipment, the alloy’s unique properties prove invaluable in a range of demanding applications.

Best used

For flash welding dies, welding wheels, electrodes for mesh welding, damper ring segments and damper rings for generators and parts for injection moulding of plastic.
