DYB501
	Material:CuZn25Al6Fe3Mn3+Graphite
	It is backed with strengthening brass that has good physical performance and good capability for casting. What's more, the brass backing has pretty good anti-erosion ability in air, fresh water and seawater. The surface is regularly and finely machined with sockets in which particular solid lubricant is filled. The product is widely used on consecutive casting and rolling machines, mine-exploiting equipments, ships, steam engine, etc.
