Mac Bronze E808
AWS E Cu Sn-C
Descriptions & Applications:
A versatile rutile coated electrode which deposits a tough overlay of fully deoxidised bronze. Designed for joining and overlaying steels, cast irons, malleable iron, bronzes, brass and copper based metals. Due to the high thermal conductivity of copper alloys, pre-heating is advisable particularly if heavy sections are involved. The electrode is recommended for overlaying and building up bearing surfaces, bushes, impellor blades, valve seats, etc.
