Our 7075 seamless tube works excellently in high temperatures so you can confidently use them in applications where the temperatures are high. This alloy has a melting point of at least 477°C and thermal conductivity of 130 W/m-K, two of the main properties that help maintain reliable performance levels even under intense temperatures. 7075 tubing users in industrial and aerospace applications where application temperatures exceed the normal usually use the 7075 aluminum tube for aircraft. However, be wary of the high temperature limits of the products because the material loses its mechanical properties beyond the limit.
