6101 aluminum aluminium flat bus bar busbar
 
Flatwise Bending Radius
 




Applicable to widths up through 6 inches in the T6,T61,T63 and T65 temper and to widths up through 12 inches for all other listed tempers. Bend radius for greater widths are subject to inquiry.

(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.

 
Aluminum Alloys and Tempers, And Conductivity % (IACS) (a) 
(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%.
