If music wire is made of 1060, its carbon content is relative high. According to the following data, 1060 has Rockwell hardness of 32. Low carbon steel are rated in the order of 1012, to 1018. To harden 1060 steel, see the following temperature ratings. (Note after quench, it is necessary to bake it at specified temperature. The baking is called tempering, or it become ceramic brittle) The following are extract from a web site..... http://www.matweb.com/SpecificMaterial.asp?bassnum=M1060K&group=General AISI 1060 Steel, oil quenched 845°C (1550°F), 480°C (900°F) temper, 13 mm (0.5 in.) round Subcategory: Carbon Steel; AISI 1000 Series Steel; High Carbon Steel Composition: Component Wt. % C 0.55 - 0.66 Fe 98.35 - 98.85 Mn 0.6 - 0.9 P Max 0.04 S Max 0.05 Hardness Rockwell B 99 Hardness Rockwell C 32 hope that helps YK RCSE-List facilities provided by Model Airplane News.
