Thermal transmission coefficients of base metals

Thermal transmission coefficients (lambda) of the most common metals (Steel, Aluminum, Copper, etc.)

No metal can be considered an insulating material, but some metals conduct heat much better than others. For example, Copper and Zinc conduct heat 22 times better than certain stainless steels! This article is part of a general article on the heat transfer coefficients

Lambda given in W / mK

  • 50 steel

  • 17 stainless steel

  • Aluminum alloys 160

  • aluminum 230

  • bronze 65

  • Copper 380

  • Pure Iron 72

  • Iron, cast 50

  • Brass 120

  • Lead 35

  • zinc 380

  1. Hello
    I was asked to re-liner a wood stove that had melted with 316 stainless steel. The craftsman told me that it is much stronger than the manufacturer's metal.
    Is the thermal transmission of stainless steel good even if less than that previously stated by the manufacturer?
    Thank you for your reply
