H90 brass is a high-quality copper alloy material with excellent mechanical properties and pressure processing properties. Its strength is similar to that of H96, but slightly higher, making it ideal for a wide range of mechanical parts and structural parts. The surface treatment properties of H90 brass are very good, and surface treatments such as metal plating and enamel can be easily applied, which makes it a unique advantage in the manufacture of bullet warhead shells.
The composition of H90 brass is very pure, with a Cu content of 880-91.0%, the content of Ni is 05%, the content of Fe is 010%, the content of PB is 003%, while ZN is the impurity of the margin. This composition gives H90 brass excellent corrosion and wear resistance, and can maintain stable performance in a variety of harsh environmental conditions.
In addition, the tensile strength of H90 brass is very high, and its tensile strength (B MPa) is 390, which means that it is able to withstand a lot of tensile forces without breaking. At the same time, its elongation is also very good, with an elongation (δ10%) 3, which indicates that it has good plastic deformation ability and can effectively relieve stress when subjected to pressure.
In conclusion, H90 brass is a high-quality copper alloy material with excellent mechanical properties, pressure processing properties and surface treatment properties. Due to its excellent properties and wide range of applications, H90 brass has become one of the important materials in many industries.
