SHG Zinc tempers and conditions
SHG Zinc is supplied in 3 conditions, soft to hard.
Compare all 3 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
sacrificial / electroplating anode | Choose for cathodic protection of steel structures and for zinc electroplating baths where Pb/Fe must stay low. | 20 | 30 | 18 | 30 HB | 28.3 % IACS |
Extruded rod / bar / tube | Use for anode rods, sputtering/spray feedstock and machined pure-zinc parts; worked structure is stronger and more ductile than cast. | 75 | 125 | 45 | 38 HB | 28 % IACS |
Rolled sheet / strip | Pick for battery cans, roofing/cladding sheet, engraving plate and photochemical blanks — rolling roughly quadruples strength but makes properties anisotropic. | 85 | 140 | 40 | 43 HB | — |

What is SHG Zinc?
SHG Zinc is Special High Grade primary zinc to ASTM B6 (UNS Z13001, also designated Zn99.995), the highest-purity zinc ingot grade at 99.99 %+ Zn. It is bought as ingot, jumbo blocks, cast anodes, rolled sheet, extrusion, wire and powder, and is the base feedstock wherever impurity control governs — die-casting alloys, galvanizing baths and brass alloying. As a pure metal it is weak (20 MPa yield, 30 MPa tensile, 20 % elongation, 30 HB) with 116 W/m·K, 28.3 % IACS and a 100 °C service limit, so it is not used for loaded parts. Prime Western zinc is the cheaper alternative where purity is not critical. SHG Zinc has a density of 7.14 g/cm³ (0.258 lb/in³), heavier than 82% of zinc alloy grades. It melts at 420°C (787 °F). SHG Zinc has a 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. Elongation at break is 20% and the elastic modulus is 96 GPa (13.9 Msi).

Chemical & Environmental3
Corrosion resistance is fair (35/100), worse than 82% of zinc alloy grades.
Sustainability4
Producing a kilogram of SHG Zinc takes about 53 MJ of energy and emits 3.7 kg of CO₂ — less than 68% of zinc alloy grades. Typical recycled content is 10%.
Manufacturability8
SHG Zinc's machinability is good (60/100, worse than 96% of zinc alloy grades); weldability fair (40/100); formability good (60/100).

Working with SHG Zinc
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 — frequently asked
What is SHG Zinc used for?
SHG Zinc 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?
SHG Zinc 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 easy to machine?
Reasonably — machinability is rated good (60/100, worse than 96% 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 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?
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 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?
SHG Zinc 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.
How much does SHG Zinc cost?
SHG Zinc is a standard-cost zinc alloy ($$), cheaper than about 71% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
