Working with SHG Zinc Extruded
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 Extruded — frequently asked
What is SHG Zinc Extruded used for?
SHG Zinc Extruded 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 Extruded?
SHG Zinc Extruded has a typical yield strength of 75 MPa (10.9 ksi) and a tensile strength of 125 MPa (18.1 ksi) — weaker than 71% of zinc alloy grades. Strength varies by condition: see the 3 listed tempers.
Is SHG Zinc Extruded easy to machine?
Reasonably — machinability is rated good (65/100, worse than 86% 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 Extruded be welded?
With care — weldability is rated fair (45/100). 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 Extruded?
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 Extruded 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 Extruded?
SHG Zinc Extruded is rated for continuous use to about 95°C (203 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
