Electrical Bare Aluminum Rectangular Wire

Introduction：Electrical aluminum rectangular wire is continuously extruded from oil-free electrical round aluminum rod with certain specification mould. The extruded electrical aluminum rectangular wire has the advantages of smooth surface, non burr, equal softness and low resistivity, etc. It can be used as finished product as well as semifinished product. The product is widely applied in electrical machines, transformers, electric welding machines and similar electrical instruments.

Production Range：

Electrical Aluminum Rectangular Wire

Production range: 4mm2-350 mm2

Narrow side size a: 0.7mm—10mm

Broad side size b: 3.0mm—38mm

Material：
Electrical aluminum rectangular wire should conform to GB5584.3-2009，the resistivity (20℃) is no more than 0.0280Ωmm²/m

Nominal Size /mm	Elongation/%
0.80＜a≤5.60	≥20

※ Narrow side size and broad side size of aluminum rectangular wire should conform to the table as follows：

Narrow Side Size/mm	Deviation	Broad Side Size/mm	Deviation
a≤3.15	±0.03	b≤3.15	±0.03
3.15＜a≤5.60	±0.05	3.15＜b≤6.30	±0.05
		6.30＜b≤12.50	±0.07
		12.50＜b≤16.00	±0.10

Angle R of aluminum rectangular wire should conform to the table as follows：

Nominal Size/mm	Radius r		Nominal Size/mm	Radius r
	Nominal Size	Deviation		Nominal Size	Deviation
a≤1.00	a/2	a≤2.50	2.44＜a≤3.55	0.80	±25%
1.00＜a≤1.60	0.5a		3.55＜a≤5.60	1.00
1.60＜a≤2.44	0.65b
If the manufacturer and user agrees with the consultations, then the radius can be semicircle or 0.8mm when broad side size of aluminum rectangular wire is more than 4.75mm.
