Aluminum is higher expansion - about 23 ppm/C, whereas steels range from 12ppm/C for alloy steel and carbon steel, 17 ppm/C for stainless 300 austenitic series, and 11 ppm/C for stainless 400 martensitic series

thermal expansion depends on Temperature and material of steel
galvanised steel is a lot more safer....... if u go by the book.... it is upto 10 times stronger than stainless steel in aluminum
Steel is a ferrous metal, aluminum is a non-ferrous metal
The joint doesn't prevent expansion and contraction but it limits the damage caused by thermal stress. It allows room for the concrete ( or steel ) to expand and contract without creating the severe cracks that would form without them.
No. Stainless Steel will resist contamination from the aluminum when they are used together.
