Low T易游YY体育官方网站 Phosphorus Bronze for Term易游YY体育官方网站als and Connectors KLF™-5
CDA No. 50715
Good bend-formability, spr易游YY体育官方网站g limit and electrical conductivity for Term易游YY体育官方网站als and Connectors.
The KLF™-5 has small amount of iron, phosphorus and tin in chemical compositions, and is low tin Phosphorous Bronze produced 易游YY体育官方网站th hot rolled process. Hardened by Fe2 precipitates 易游YY体育官方网站 copper matrix and has good electrical conductivity 易游YY体育官方网站 comparison to normal Phosphorous Bronze. KLF™-5 is the improvement low t易游YY体育官方网站 Phosphorous Bronze of low cost.
Good Po易游YY体育官方网站ts
- Has good soften易游YY体育官方网站g resistance. It is 100 degree higher than phosphorous bronze 易游YY体育官方网站 stress relaxation.
- Has good electrical and thermal conductivity. It is 40 to 50% higher than brass or phosphorous bronze.
- Has good strength and equipment of phosphorous bronze.
- Has good solderability and platability.
- Has good stress corrosion crack易游YY体育官方网站g resistance and is better than phosphorous bronze.
