KLF125 CDA No. 64730 |
|
KFC125
is an alloy containing Ni and Si and Sn with the same excellent
mechanical properties as alloy 42. It is strengthened by
precipitates of Ni2Si and by solid solution hardening
of Sn. |
|
Features |
|
1.
High
strength and good multiple bendability equivalent to Alloy 42.
2.
Thermal
and electrical conductivity, over ten times than that of Alloy
42.
3.
Excellent
heat resistance up to approximately 7750K.
4.
Good
solderability and soldering weatherability.
5.
Good
stress corrosion cracking resistance, corrosion resistance and
platability.
