Designed for hardness and heat resistance, these alloys often trade off some conductivity.
To put steel's performance into perspective, here is how it stacks up against other popular metals: Thermal Conductivity ( Relative Performance Highest (The Gold Standard) Pure Copper Excellent (Electrical/Heat Sinks) Pure Aluminum Good (Lightweight Heat Sinks) Brass Cast Iron Comparable to Carbon Steel Carbon Steel Fair Stainless Steel Low Key Takeaway for Your Project Thermal Conductivity Of Metals List Steel
Stainless steel is the best choice among common metals because its low conductivity prevents heat from escaping quickly. Designed for hardness and heat resistance, these alloys
