| This is a fairly high-grade, high-carbon steel wireto specification ASTM A-228. It is a “cleaner” steel than hard drawn and exhibits a better fatigue life. Today, music wire is made by either direct drawing from rod or lead patenting. As a guide, most stocked music wire thicker than 0.0625" is more likely to have been direct drawn. |
Although very high in tensile strength, must be capable of wrapping around itself without showing signs of cracking. 156 ft. of .049" dia. wire per lb., 46 ft. of .090" dia. wire, per lb. 22 Ga.
