Abstract

The invention discloses a high zinc copper alloy cutting wire rod and a production technology. The high zinc copper alloy cutting wire rod is prepared through the following materials of the weight parts: pure copper 55-80 parts, aluminum 8-12 parts, iron 1-5 parts, and silicon 2-4 parts. The production technology comprises steps of melting, cold stretching, annealing, pickling, flattening, finishing and straightening, one cutting and sizing, packaging and warehousing. The copper alloy wire rod wire rod disclosed by the invention is good in the mechanical property, high in conductivity, simple in process and low in the production cost. The high zinc copper alloy cutting wire rod is applicable to the high-low voltage electric appliance, the switch contactor, the distribution device, the bus groove, etc and has advantages of low conductivity and big in bending.

Description

Technical field [0001] The invention involves the field of copper alloy wires, which specifically involves a high -zinc and copper alloy cutting wire and its production process. Background technique [0002] Copper alloy wires are mainly used on one line (large current phase lines, zero lines, and ground wires are used in copper alloy wires). The connection of one -piece device on a larger current on the electrical cabinet is copper alloy wire.Copper alloy wires include tin -plated and naked copper alloy wires. Generally, tin -plated treatment and flowering or electric cream are generally done at the connection between the copper alloy wires in the electrical cabinet.There are heating shrinking pipe protection, and some are painted with insulation.The most important thing to use copper alloy wires is the load traffic. According to the current, the appropriate copper alloy wire is selected. [0003] The use of copper materials in the power and communication industry is very wide...
