Abstract

In a method of making electrical contacts from powder metal (see Group XXII), the powder may be an aggregate of a noble metal such as silver and one or other conductive metals such as nickel, cobalt, tungsten or molybdenum. The proportions may be 70 per cent silver and 30 per cent balance of other metal or metals nickel, cobalt, tungsten or molybdenum.
