Brass is an alloy of copper and zinc, in proportions which can be varied to achieve different colours and mechanical, electrical, acoustic and chemical properties, but copper typically has the larger proportion, generally 2⁄3 copper and 1⁄3 zinc. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. rass has long been a popular material for its bright goldlike appearance and is still used for drawer pulls and doorknobs. It has also been widely used to make sculpture and utensils because of its low melting point, high workability (both with hand tools and with modern turning and milling machines), durability, and electrical and thermal conductivity. Brasses with higher copper content are softer and more golden in colour; conversely those with less copper and thus more zinc are harder and more silvery in colour. Brass is still commonly used in applications where corrosion resistance and low friction are required.
Blind Flange, also called blind flange, is a pipe fitting used in pipeline systems. It is actually a solid flange, which is mainly used to block the end of the pipeline in the pipeline system to isolate and cut off the flow of the medium.Blind Flanges usually have the same connection size and bolt hole distribution as standard flanges so that they can be connected to other flanges on the pipeline by bolts. Its structure is simple, which is a round metal plate. The thickness varies according to the pressure used and the pipeline specifications. The materials are generally carbon steel, stainless steel, alloy steel, etc. to adapt to different working environments and media requirements.
