Abstract
Abstract A method of making Ag, Au or Cu thin alloy wire comprises a first step of melting alloy containing Be with 0.001 through 1% by weight, a second step of jetting the melted alloy into a thin wire configuration through a small opening and a third step of curing the jetted alloy of a wire configuration in a fluid so that a thin alloy wire having about 0.01 through 0.2 mm diameter with simple processes and high yield.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
74 words
A method of making an alloy wire comprising: (a) melting an alloy, said alloy containing 0.001 through 0.5% by weight of Be, the remainder being Au; (b) jetting the thus melted alloy into a thin wire configuration through a small opening; and (c) curing the thus jetted alloy by moving said jetted alloy in a fluid situated along an inner surface of a cylindrical wall of a cylindrical container while rotating said cylindrical container.
Claim 2
Independent Claim
74 words
A method of making an alloy wire comprising: (a) melting an alloy, said alloy containing 0.001 through 0.5% by weight of Be, the remainder being Au; (b) jetting the thus melted alloy into a thin wire configuration through a small opening; and (c) curing the thus jetted alloy by moving said jetted alloy in a fluid situated along an inner surface of a cylindrical wall of a cylindrical container while rotating said cylindrical container.
Claim 3
Independent Claim
73 words
A method of making an alloy wire comprising: (a) melting an alloy, said alloy containing 0.003 through 2.0% by weight of Be, the remainder being Cu; (b) jetting the melted alloy into a thin wire configuration through a small opening; and (c) curing the thus jetted alloy by moving said jetted alloy in a fluid situated along an inner surface of a cylindrical wall of a cylindrical container while rotating said cylindrical container.
Claim 4
Independent Claim
73 words
A method of making an alloy wire comprising: (a) melting an alloy, said alloy containing 0.003 through 2.0% by weight of Be, the remainder being Cu; (b) jetting the melted alloy into a thin wire configuration through a small opening; and (c) curing the thus jetted alloy by moving said jetted alloy in a fluid situated along an inner surface of a cylindrical wall of a cylindrical container while rotating said cylindrical container.
Claim 5
Dependent Claim
37 words
The method of making an alloy wire according to claim 2, wherein said alloy contains Be within 0.003 through 0.5% by weight for making a copper alloy conductor wire having a conductivity of at least 60% IACs.
Claim 6
Independent Claim
74 words
A method of making an alloy wire comprising: (a) melting an alloy, said alloy containing 0.001 through 0.5% by weight of Be, the remainder being Ag; (b) jetting the thus melted alloy into a thin wire configuration through a small opening; and (c) curing the thus jetted alloy by moving said jetted alloy in a fluid situated along an inner surface of a cylindrical wall of a cylindrical container while rotating said cylindrical container.
Claim 7
Independent Claim
74 words
A method of making an alloy wire comprising: (a) melting an alloy, said alloy containing 0.001 through 0.5% by weight of Be, the remainder being Ag; (b) jetting the thus melted alloy into a thin wire configuration through a small opening; and (c) curing the thus jetted alloy by moving said jetted alloy in a fluid situated along an inner surface of a cylindrical wall of a cylindrical container while rotating said cylindrical container.
