CarTech® TOPHET® Alloy A

Generic Family: Nickel - Wrought - Ni-Cr Alloy • Supplied by: Carpenter Technology Corporation

CarTech Tophet alloy A, an 80% nickel 20% chromium alloy, has for half a century been satisfactorily used at temperatures up to 2150°F (1175°C).

Quality manufacturers of electric furnaces, appliances, and other resistance heating applications specify CarTech Tophet alloy A with confidence. Resistance to most acids and alkaline solutions make CarTech Tophet alloy A valuable to chemical industries where it has found wide use in baskets, belts, and other hardware.

CarTech Tophet alloy A is the most resistant of all the CarTech Tophet alloys in a carburizing atmosphere.

CarTech Tophet alloy A, having the advantages of being nonmagnetic and having high resistivity (650 ohms cm/f) has been used in wire-wound resistors in ultrafine sizes. The temperature coefficient for resistance (TCR) for standard CarTech Tophet alloy A in the range of 25/250°C is 0.000085 ohms/ohm/°C (85 parts per million).
