Product Description

The 660 bronze bar is made with a combination of copper and tin. It is considered as being a high leaded tin/bearing bronze. Because it is highly versatile, it is a popular product to use. It is a medium range bronze and can be used for a variety of applications. It has excellent hardness and strength and isn’t easily worn down. The machining capabilities of this bronze are excellent and it has great antifriction qualities. Because it has great resistance in sea water, it is frequently used in marine applications. It also isn’t subject to dezincification. 660 bronze has good resistance to brine as well, making it ideal for applications for pump and valve components. However, its resistance level is lower than that of PB1 Phosphor bronze.

Other applications that this product can be used for include bushings and bearings that aren’t under heavy load and speed, and that has sufficient lubrication. Joining techniques that can be used for this metal include soldering and brazing. It’s not recommended for coated metal arc welding, gas shielded arc welding or oxyacetylene welding be used for this purpose. Machining can also be used for 660 bronze, which has a 70 machinability rating.

The liquidus melting point for 660 bronze alloys is 1790 degrees F and the solidus melting point is 1570 degrees F. The fabrication of this metal is best for applications that are light duty. It is quite easy to machine this product. Compared to other alloys, this metal has great conformity to journal irregularities and doesn’t rely on lubrication. This product is frequently used in industries like automotive and industrial.
