Toughmet Nickel Bronze __exclusive__ Info

In ASTM G98 galling tests, ToughMet 3 exhibits galling threshold > 300 MPa (vs. ~140 MPa for Al-bronze and ~70 MPa for 316 stainless steel). This makes it suitable for unlubricated sliding contacts.

| Grade | Composition (wt.%) | Temper | Typical UTS (MPa) | Hardness (HRC) | Key Feature | |-------|--------------------|--------|------------------|----------------|---------------| | ToughMet 3 | Cu-15Ni-8Sn | AT (age-hardened) | 760–860 | 26–32 | High ductility, corrosion resistance | | ToughMet 3 | Cu-15Ni-8Sn | TS (mill-hardened) | 1,000–1,200 | 34–40 | Maximum strength, wear resistance | | ToughMet 2 | Cu-9Ni-6Sn | AT | 620–760 | 20–28 | Lower cost, moderate strength | toughmet nickel bronze

Because of this unique combination of properties, ToughMet has become the material of choice for several demanding industries: In ASTM G98 galling tests, ToughMet 3 exhibits
