CSA C49.3-10 pdf free download.Aluminum 1350 wire , annealed and intermediate tempers , for electrical purposes.
H temper — a property of wire whose strength is increased by strain hardening through cold working in a drawing operation,
(1) The H is always followed by two digits. The first digit following the H” indicates the specific combination of further operations, as follows:
(a) Hi — Strain hardening only, without supplementary thermal treatment; and
(b) H2 — Strain hardened and then partially annealed.
(2) The second digit following the H indicates the final degree of strain hardening. The range is from -o – (fully
annealed) to 9 (fully hard). The following are common tempers:
(a) 0 — fully annealed;
(b) 2— 1/4 hard;
(c) 4—1/2hard;
(d) 6 — 3/4 hard;
(e) 8 — fully hard; and
(f) 9 — fully hard, exceeding fully hard temper “8 by 14 MPa.
Intermediate temper — the range of tempers between fully annealed “0” and fully hard “9”.
(1) Intermediate temper includes 1/4, 1/2, and 3/4 hard tempers.
(2) Foi example, H26” is a stran-hardened wire produced through cad working with subsequent heat treatment to a final temper of 3/4 hard.
4 Requirements for wire
4.1 General
The wire shall be free from all imperfections not consistent with good manufacturing practice.
4.2 WIre sizes
Wire sizes shall be expressed as the diameter of the wire in millimetres, measured to the nearest 0.01 mm.
4.3 Diameter and permissible variations
The diameter of the wire shall not vary from its nominal diameter by more than the amount specified in
Table 1.
The diameter of the wire shall be determined in accordance with the method specified in Clause 5 of
For the purpose of verifying compliance with this requirement, the diameter shall be determined by taking two measurements at right angles at the same cross-section.
4.4 Joints
4.4.1 Joints made before final drawing
joints may be made in rods and wire before final drawing, in accordance with good manufacturing practice.
4.4.2 Joints made during final drawing or in finished wire
joints may be made during final drawing or in the finished wire by
(a) electric butt welding;
(b) electric butt cold-upset welding; or
(C) cold pressure welding.
Not more than two such joints shall be present in any reel or coil of the nominal specified weight.
4.4.3 Tension test (optional)
joints as permitted in Clause 4.4.2 may be subjected to tension tests. When such tests are performed, the minimum tensile requirements specified in Table 2 shall be met.
Note: Sampling is sublect to agreement between the purchaser and the manufacturer.
4.5 Tensile properties
The wire shall conform to the requirements specified in Table 2.CSA C49.3-10 pdf free download.
