CAC65
|
|
CAC65
is an alloy for terminals and connectors with equivalent
mechanical properties as phosphor bronze; containing a small
amount of Ni, Si and Sn, strengthened by precipitation hardening
and solid solution hardening. It has high reliability with
excellent electrical conductivity and heat resistance compared
to phosphor bronze. |
|
Features |
|
1.
Higher
electrical conductivity than 45% IACS. Temperature of the resin
in its connectors under high current condition is smaller than
that of phosphor bronze.
2.
Excellent
softening resistance and stress relaxation resistance.
3.
Excellent
current leak resistance if its connectors are exposed in the
dewing atmosphere.
4.
Good
solderability and good adhesion solder.
5.
Excellent
stress corrosion cracking resistance, corrosion resistance and
platability.
