Webster Hardness Tester is the best choice for mechanical testing on aluminum alloy material, it is conform to Chinese nonferrous standard YS/T420-2004 and US standard ASTM B647-84(2000).
Using Scope:
Especially suitable in production site,sales site or construction site for quickly testing on bulk products with non-destructive quality inspection piece by piece.
Besides aluminum alloy material, it is also suitable to test red copper, brass, soft copper etc.
Application:
- W-20: General Model, suitable for common aluminum materials;
- W-20A:Suitable for aluminum materials with thickness ≤13mm;
- W-20B:Suitable for aluminum tube with inner dia.≥6mm;
- W-B75:Suitable for brass tube, brass strip;
- W-BB75: Suitable for red copper tube, red copper strip;
- W-B92:Suitable for soft stainless steel, cold-rolled strip.

- Indenter: Re-engineerred with advanced material and new production technology manufactured, higher hardness, long service life, good interchangeability;
- Indicator Hand: High strength indicator hand, less likely to be bent by long-term using or mis-operation;
- Dial Glass: High strength, high toughness, uneasy to be broken or scratched;
- Handle: Forged aluminum alloy handle with fine anodized finishing, high resistance to abraision and stain;
- Hardness Blocks: Tested by standard Rockwell hardness tester, attached with test report;
- Good Stability: Stable full scale point, stable calibration point, indicator never glides;
- Easy Conversion: Results can be converted to Vickers, Rockwell and Brinell.
