6101 T6 Aluminum Flat Busbar Bus Bar

6101 T6 Aluminum Flat Busbar Bus BarPure 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) Typical conductivities of 6101 alloys from Standards of The Aluminum Association. The conductivity of 6063·T6 alloy pipe for outdoor service may be taken as 55.% lACS for current ratings, per NEMA Standard.
(b) To obtain de resistance at 20"'C in microhms multiply table value by length in feet and divide by cross sectional area in sq. in.
(c) Increasing by 0.018 for each 100"C above 70'C (specific heat).
(d) The higher of a pair of coettlclents corresponds to the higher vafue of the pair of conductivity values.AluminumAlloysandTempers,AndConductivity%(IACS)(a)6061-

(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%.
