QuCu84 TIG Welding Wire – Silicon Bronze CuSi2 / ERCuSi-A (2.1522)
QuCu84 TIG Welding Wire – Silicon Bronze CuSi2 / ERCuSi-A (2.1522)
QuCu84 is the ductile silicon bronze: EN ISO 24373 S/G Cu 6511 (CuSi2Mn1) · AWS A5.7 ERCuSi-A · material no. 2.1522. With 1.8 % silicon it is softer than QuCu82 (62 HB) — in return it offers 45 % elongation, the highest figure in quada's entire copper range.
That makes it the choice when the seam has to yield: on thin sheet, on low-zinc brasses (CuZn5, CuZn10, CuZn15) and on build-ups that are later formed or heavily loaded. Also suitable for build-ups on unalloyed steel and cast iron.
Recommended base materials
- Copper and low-alloy copper alloys
- CuZn5, CuZn10, CuZn15 (brass)
- Silicon bronzes
- Build-up welding on unalloyed and low-alloy steel, cast iron
Typical applications
- Joint welding on copper and brass
- Build-up welds requiring high formability
- Thin sheet and components with stress in the seam
- Build-ups on steel and cast iron
Properties and advantages
- A 45 % elongation — the most ductile copper filler in quada's range
- 62 HB, Re 285 MPa · Rm 530 MPa
- Softer and tougher than QuCu82 (Si 3 %)
- Also usable on steel and cast iron
TIG advantage: For larger seams on copper and brass. Ø 1.6 mm.
TIG form: for manual repair welding.
