Abstract
An aluminum wire includes a strand main body, an inner layer, and an outer layer. The strand main body includes aluminum wire or an aluminum alloy wire. The inner layer includes Zn, a Zn alloy, Ni, or an Ni alloy and covers the outer circumferential surface of the strand main body. The outer layer includes Sn or an Sn alloy and covers the outer circumferential surface of the inner layer. In the aluminum wire, the pinhole ratio in the outer layer is no more than 4% and/or the thickness of the inner layer is at least 0.3 μm.
Claims7
A wire harness comprising:
- an electrical wire;
- a protective member covering an outer circumferential surface of the electrical wire;
- a connector connected to the electrical wire exposed from the protective member at a harness end portion;
- and
- a tubular braided wire that is fixed to an end portion of the protective member and an end portion of the connector, and that covers the outer circumferential surface of the electrical wire exposed from the protective member,
- wherein the braided wire includes a plurality of strands that are braided,
- the strands are each constituted by an aluminum-based strand that includes:
- a strand main body portion constituted by an aluminum wire or an aluminum alloy wire;
- an inner layer constituted by Zn or a Zn alloy, or Ni or a Ni alloy and covering an outer circumferential surface of the strand main body portion;
- and
- an outer layer constituted by Sn or a Sn alloy and covering an outer circumferential surface of the inner layer,
- wherein the outer layer has a pinhole ratio of 4% or less, and
- the inner layer has a thickness of 0.3 μm or more.
