This material is known for its exceptional strength and toughness. It can be hot worked but should not be cold worked. Additionally, 630 bronze maintains its strength even at elevated temperatures. Soldering and oxyacetylene welding are both rated as poor, brazing is fair. Other forms of welding are rated as good for 630. It is typically used in aerospace and marine applications such as valve stems, high strength bushings, valve seats and guides, gears, cams, nuts, shafts, and ship propellers.
