TENSILE STRENGTH OF METALS Alloy steels can be made with tensile strengths as high as 300,000 pounds per square inch. Some carbon steels are given below according to "points": Pounds per Square Inch Steel, 10 point................ 50,000 to 65,000 20 point..................... 60,000 to 80,000 40 point..................... 70,000 to 100,000 60 point..................... 90,000 to 120,000 Iron, Cast..................... 13,000 to 30,000 Wrought...................... 40,000 to 60,000 Malleable.................... 25,000 to 45,000 Copper......................... 24,000 to 50,000 Bronze......................... 30,000 to 60,000 Brass, Cast.................... 12,000 to 18,000 Rolled....................... 30,000 to 40,000 Wire......................... 60,000 to 75,000 Aluminum....................... 12,000 to 23,000 Zinc........................... 5,000 to 15,000 Tin............................ 3,000 to 5,000 Lead........................... 1,500 to 2,500 CONDUCTIVITY OF METALS (Based on the Value of Silver as 100) Heat Electricity |
