Price range: $1.03 through $3.43 ( Not real price )
HS221 Tin‑Brass Brazing Rod Copper alloy gas welding wire, 1 m length, diameters 1.6 mm, 2.0 mm, 2.5 mm, 3.0 mm, 4.0 mm, 5.0 mm, 6.0 mm, melts 890‑905°C. Alloy Cu59‑61%‑Sn‑Si‑Zn, 400 MPa tensile strength. Works for oxy‑acetylene / argon‑arc brazing for steel, cast iron & carbide tool joining.
This is HS221 tin‑brass brazing rods copper alloy gas welding wire, available round rod diameters: 1.6 mm, 2.0 mm, 2.5 mm, 3.0 mm, 4.0 mm, 5.0 mm, 6.0 mm, uniform rod length: 1000 mm (1 meter)
Note: Only suitable for oxy‑acetylene welding or argon‑arc welding. It cannot be melted by simple flame guns. Adding copper brazing powder improves molten‑metal flow performance.
Specification:
| Product Name | Tin‑Brass Brazing Wire (Brazing Rod) Copper alloy gas welding |
| Model | HS221 |
| Melting Point | 890 °C‑905 °C |
| Chemical Composition | Cu: 59‑61%, Sn: 0.5‑1.0%, Si: 0.15‑0.35%, Zn: Balance |
| Tensile Strength | 400 MPa |
| Elongation | 25% |
| Application Scope | For brazing steel, cast iron, and embedding carbide‑alloy cutting tools. Also usable as surfacing material for low‑pressure valve sealing faces and light‑load wear‑resistant surfaces. |
Features:
- Multiple round‑rod diameter options from 1.6 mm up to 6.0 mm; every rod is 1 m long.
- Strict alloy ratio of copper, tin, silicon and zinc guarantees stable brazing performance.
- Mechanical metrics: 400 MPa tensile strength and 25% elongation for tough, ductile joints.
- Process restriction: Ordinary flame guns cannot melt this rod; oxy‑acetylene or argon‑arc welding equipment is mandatory.
- Brazing flux powder is required to boost the fluidity of the molten filler metal.
- Dual‑purpose: dissimilar‑metal brazing and wear‑resistant surface overlay welding.
Practical Use‑Case Summary
- Braze steel‑cast‑iron assemblies
- Bond carbide cutting tips onto tool bodies
- Build‑up sealing surfaces for low‑pressure valves
- Deposit light‑duty wear‑resistant overlay layers on mechanical parts
