Metal Strengths


Metal Strengths

The strength of metals is most often compared by their tensile strengths. These numbers are Newtons per square millimetre and represent the relative strength of each metal compared to another.  The range of numbers indicates the variations caused by various alloys.

Tin                      19
Lead                14 – 32
Solder 60/40        48
Zinc                120 – 246
Aluminium       120 – 246
Copper            220 – 270
Brass              340 – 540
Mild steel         500 – 750
Stainless steel  740 – 970

These figures may be of interest in considering what frame to place around a free hanging stained glass panel.
