Description
Patented July 25, 1933 UNITED STATES TPATENT OFFICE HERBERT o. JENNISON, or
BRIDGEIPORT, CONNECTICUTIL'ASSIGNOR TO THE AMERICAN CUT COPPER BASE ALLOY No Drawing. Original application filed November 3, 1932, Serial No. 641,040. Divided and this application filed June 8, 1933.
This invention relates to a copper base alloy, particularly to an alloy which has good electrical conductivity, high strength and hardness.
. This application is a division of my prior application Serial Number 641,041, filed No vember 3, 1932.
I have found that by adding cadmium in amount from approximately 0.01% to 2% to a copper base alloy containing approximately from 0.01% to 3.5% silicon, 1.0% to zinc, 0.01% to 3.5% manganese and balance copper, the cadmium materially increases the strength and hardness without materially decreasing the electrical conductivity. Also the addition of aluminum up to a certain amount increases the deoxidation and im-,
proves the hot working qualities as well as increasing the hardness and toughness. The aluminum may be added in amount from 0.01% to approximately 6.0%. minum tends to decrease the electrical con.- ductivity, if the alloy is to be used for elec- 5 trical purposes the amount of aluminum added would not ordinarily go over 0.5%, but for some of. the mechanical uses it mightgo as high as 6%.
This improved alloy has high tensile strength which is increased when hard drawn' into wire, and it also has hardness, toughness and high electrical conductivity. As it has improved hot working qualities it can'be readily hot rolled, and it draws easily on 5 wire machines as it can be drawn without 40 alloy has high strength seriously damaging the dies, which is a serious objection of the usual alloys having high tensile strength and electrical conductivity as they tear out the dies very rapidly. As this and conductivity it is very good for cables or stranded conductors.
This alloy is also adapted for numerous other uses. For example, it is adapted for use in making cold headed bolts, or hot headed bolts, U-bolts, or saddles, together with washers and nuts for the same. making metal wool by the by drawing into fine wire, etc.
This alloy is further suitable for welding and for use as welding rods. It may be auto- It is also good for cutting process, or rolling into tinsel,

genously welded, spot welded as well as being used as a welding rod in all types of welding. It. may also be brazed.
no to its improved hot working qualities it may be'readily extruded, hot forged and hot pressed.
In addition to the hot working it may be made into wire,'rods. tubes, sheets and shapes, and may also be into cups and other forms of drawn metal articles.
Also on account of its high electrical conductivity and hardness it may be used for electrodes in spot welding machines.
Having thus set forth the nature invention, what I claim is:
copper base alloy comprising approximately 1.0% to 15% zinc, 0.10% to 3.5% silicon, 0.10% to 3.5% manganese, 0.10% to 2.0% cadmium, 0.10% to 6% aluminum, and balance copper.
of my 2. A copper base alloy comprising approxance copper.
4. A cold drawn wire composed of a. copper base alloy comprising approximately 1.0% to 15% zinc, 0.10% to 3.5% silicon, 0.10% to 3.5% manganese, 0.10% to 2.0%
to 0.5% aluminum, and balance copper.
