| Suggested Uses | |||||||
| White Metal, high tin alloys with excellent casting characteristics for tailored and elaborate filgree pieces and excellent plating adhesion. Increasing the antimony content gives greater hardness for polishing and fluidity for reproducibility. Increasing the lead content improves ductility if forming is required. These alloys have a low casting temperature for long mold life. The pasty range can be selected for variety of casting sizes. All lend themselves in different degrees to bending and pronging. Excellent for rings, pins, bangles and earrings. |
