Mac Bronze E809
AWS E Cu Sn Tin Bronze
Descriptions & Applications:
A superior rutile coated tough 14% tin bronze electrode for joining and overlaying steels, cast irons, malleable irons, bronzes and copper based metals. Due to the high thermal conductivity of copper and copper alloys pre-heating is advisable in certain instances particularly where heavy sections are involved. Highly recommended for bearing surfaces and for wear facing against sea water corrosion.
