C656 Silicon Bronze Electrode


INTRODUCTION

Aufhauser Silicon Bronze Electrode contains approximately 3% silicon plus small percentages of manganese and tin. It is an excellent choice for applications involving welding cast iron to steel, or where the part is exposed to corrosives. Silicon Bronze weld deposits are strong, ductile, and crack resistant - even when welding on dirty, oily, burned cast or malleable parts. The high silicon content allows the Silicon Bronze Electrode to be used as a welding or brazing electrode.

ADVANTAGES

  • Welding copper-silicon alloys, cast iron, malleable iron, galvanized iron, copper-base alloys and dissimilar metals
  • Surfacing area subjected to corrosion

GENERAL INFORMATION

Chemical Composition
Copper Tin Manganese Iron Silicon Aluminum Lead Other*
Remainder 1.5 1.5 0.50 2.4 - 4.0 0.01 0.02 0.50

Note: Copper contains Silver. All values are maximum percentage, unless shown in range. * Total Other includes Zinc, Nickel, Phosphorus = 0.50%

ADDITIONAL INFORMATION

Copper and its alloys require a relatively high heat input with shortened welding time. Higher preheat temperatures and faster welding rates than for steel are necessary.
