Product Description

6101 T6 Aluminum Flat Busbar Bus Bar

Pure aluminum has a conductivity of about 65 percent of the International Annealed Copper Standard (lACS). Aluminum can be produced 99.99 percent pure; however, this purity is costly to achieve and the mechanical properties are low.

After World War II, a new conductor alloy, 6101, was developed wbich had considerably higher yield strength and better creep resistance than 1350. The alloy contained magnesium and silicon for high mechanical strength without significant reduction in conductivity. The strength of this alloy (6101) is obtained by suitable heat treaunents, occasionally combined with some cold work.

Other aluminum alloys may be used for bus conductors. However, they should be used with care since conductivity and mechanical properties can be greatly affected by small amounts of alloying elements.

(a) For alloys not shown. obtain conductivities from Table 13·2, and interpolate from the listed values.
 
(b) Per note on Table 1;3.2, 55% conductivity is much used as design basis for 6063·T6 alloys for tubes, hence coefficients should be taken from the column, headed 55%.
