ZINC

TYPES OF ZINC:
Zinc Aluminum: These alloys, such as ZA-8 and ZA-27, contain zinc as the primary component along with varying amounts of aluminum. They offer good mechanical properties and corrosion resistance
Electroplated Zinc: Zinc is often electroplated onto other metals, such as steel, to provide corrosion resistance or for decorative purposes.
Pure zinc: It is a bluish-white metal with relatively low melting and boiling points. Pure zinc is not commonly used in industrial applications due to its softness and low strength.

BRASS
PROPERTIES
-
-
-
Brass exhibits excellent corrosion resistance,
-
also has good thermal conductivity, meaning it can efficiently transfer heat.
Brass is relatively easy to machine, making it suitable for precision components and intricate designs.

TYPES
Alpha Brass: These brasses contain zinc as the major alloying element along with copper. They are typically used for general-purpose applications due to their good machinability and corrosion resistance.
White Brass: This is a brass alloy containing high zinc content, giving it a whitish appearance. It is used for decorative purposes and in musical instruments.
Naval Brass: This brass alloy contains zinc, copper, and a small amount of tin. It is resistant to corrosion in seawater and is commonly used in marine applications.
Red Brass: Also known as gunmetal, red brass contains a higher proportion of copper than zinc. It has a reddish color and is used for fittings, valves, and other applications requiring corrosion resistance.
