Zinc Alloy Prime Western Zinc vs SHG Zinc
Zinc Alloy · grade comparison
Zinc Alloy Prime Western Zinc and SHG Zinc are both zinc alloy grades. Prime Western Zinc is the stronger of the two: tensile strength 35 MPa (5.08 ksi) against 30 MPa (4.35 ksi) for SHG Zinc, about 17% more. In exchange, SHG Zinc is the more ductile: elongation 20% versus 5% for Prime Western Zinc, and Prime Western Zinc is harder (32 HB vs 30 HB). On the shop floor, Prime Western Zinc machines more easily (very good vs good) and SHG Zinc welds better (fair vs poor).
Prime Western ZincChoose it when strength drives the design, or when the part is machined in volume.
SHG ZincChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
Prime Western Zinc vs SHG Zinc: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all zinc alloy grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

Prime Western Zinc vs SHG Zinc — frequently asked
Is Prime Western Zinc stronger than SHG Zinc?
Yes. Prime Western Zinc has a typical tensile strength of 35 MPa (5.08 ksi) against 30 MPa (4.35 ksi) for SHG Zinc — about 17% more.
Which is cheaper, Prime Western Zinc or SHG Zinc?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, Prime Western Zinc or SHG Zinc?
Prime Western Zinc. Its machinability rates very good (75/100) against good (60/100) for SHG Zinc; for welding the order is SHG Zinc first (fair, 40/100) then Prime Western Zinc (poor, 20/100).
