STRESS RELAXATION RESISTANT BRASS |
摘要 |
An alpha brass (copper/zinc alloy with less than 39%, by weight, of zinc) stock alloy has controlled additions of nickel, tin and phosphorous. The combination of nickel and tin increase resistance of the alloy to elevated temperature stress relaxation. As a result, spring contacts formed from alloys of the invention maintain a higher percentage of initially imposed stress at elevated temperatures, in the range of 125° C. to 150° C., for significantly longer times than other brass alloys of comparable strength. |
