Abstract

1,172,813. Sintered copper compacts. BRITISH INSULATED CALLENDER'S CABLES Ltd. July 18, 1967 [July 19, 1966], No.32270/66. Heading C7D. Copper compacts are made by hot pressing copper powder, preferably less than 10 microns, having an oxide coating such that the oxygen content is less than 0À3% the copper powder being produced by heating the powder in a reducing atmosphere below the sintering temperature e.g. at 150‹-250‹C. to produce a powder with an oxygen content below 0À1%. If the powder is not hot pressed immediately after reduction it should be stored in a non-oxidizing atmosphere. The reduction is carried out in hydrogen, cracked ammonia, town gas, methane or propane and the compaction may be carried out at 500‹C. in a standard press or by extrusion. The compact may then be rolled and/or drawn into wire or strip. The copper powder preferably contains at least 0À1% carbon e.g. 0À1-0À2%.
