Working with SHG Zinc Anode-Cast
Is SHG Zinc easy to machine?
Cuts easily but smears — use sharp, high-rake, polished tools, high speed, light feeds and no lubricant needed beyond a light oil; avoid built-up edge.
Can SHG Zinc be welded?
Rarely welded; TIG/oxy-fuel with pure-zinc filler works on rolled sheet, but the low boiling point (907 °C) means heavy zinc-oxide fume — extraction is mandatory.
Can SHG Zinc be formed, bent or molded?
Cast ingot is brittle; rolled zinc bends and deep-draws best at 40–120 °C and must be formed with the grain direction in mind because of strong basal texture.
What surface finishes work on SHG Zinc?
Not anodisable — protect with chromate/trivalent passivation, phosphate + paint, or leave to weather to a self-limiting carbonate patina; solders readily with zinc-chloride flux.

SHG Zinc Anode-Cast — frequently asked
What is SHG Zinc Anode-Cast used for?
SHG Zinc Anode-Cast is typically used for hot-dip galvanizing baths, zamak/ZA alloy feedstock, brass and bronze alloying and zinc oxide production. In short: highest-purity primary zinc; base stock for zamak; pure metal, low strength.
What is the yield strength of SHG Zinc Anode-Cast?
SHG Zinc Anode-Cast has a typical yield strength of 20 MPa (2.9 ksi) and a tensile strength of 30 MPa (4.35 ksi) — weaker than 96% of zinc alloy grades. Strength varies by condition: see the 3 listed tempers.
Is SHG Zinc Anode-Cast easy to machine?
Reasonably — machinability is rated good (58/100, worse than 100% of zinc alloy grades). Cuts easily but smears — use sharp, high-rake, polished tools, high speed, light feeds and no lubricant needed beyond a light oil; avoid built-up edge.
Can SHG Zinc Anode-Cast be welded?
With care — weldability is rated fair (40/100). Rarely welded; TIG/oxy-fuel with pure-zinc filler works on rolled sheet, but the low boiling point (907 °C) means heavy zinc-oxide fume — extraction is mandatory.
What surface finishes work on SHG Zinc Anode-Cast?
Not anodisable — protect with chromate/trivalent passivation, phosphate + paint, or leave to weather to a self-limiting carbonate patina; solders readily with zinc-chloride flux.
Can SHG Zinc Anode-Cast be formed, bent or molded?
Cast ingot is brittle; rolled zinc bends and deep-draws best at 40–120 °C and must be formed with the grain direction in mind because of strong basal texture.
What is the maximum service temperature of SHG Zinc Anode-Cast?
SHG Zinc Anode-Cast is rated for continuous use to about 100°C (212 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
