Title:
ALUMINUM ALLOY WIRE
Document Type and Number:
Japanese Patent JP2015133324
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an aluminum alloy wire and an aluminum alloy stranded wire each having excellent corrosion resistance, an insulated electric wire using the alloy stranded wire as a conductor, and an electric wire with a terminal including the insulated electric wire.SOLUTION: There is provided the aluminum alloy wire for use in a conductor of an electric wire for an automobile, which has a cross sectional area of 8 mmor less, and which includes a coating layer on an external surface of an end of the alloy wire to which a terminal member made of copper or copper alloy is attached. The outermost layer of the coating layer is composed of tin or a tin alloy. In the aluminum alloy wire having the cross sectional area of 8 mmor less, electric corrosion is likely to occur in the vicinity of a terminal member made of copper or copper alloy since an exposed area of copper or copper alloy with respect to an exposed area of aluminum alloy becomes larger. However, since tin or tin alloy exists between the aluminum alloy and the terminal member made of copper or copper alloy, electric corrosion between aluminum alloy and terminal member can be reduced.
