Understanding Low-Melting-Point Brass
Low-melting-point brass typically includes alloys with a zinc content that allows them to melt at lower temperatures (around 900°C to 950°C compared to conventional brasses). This characteristic makes them easier to process, especially in complex machining applications where other metals may prove difficult to form. The unique composition of low-melting-point brass involves varying ratios of copper and zinc, which offers versatility in performance and quality.
Composition and Properties
Brass alloys consist primarily of copper and zinc, with low-melting-point (LMP) brass characterized by its favorable melting range. The addition of other elements, such as lead or tin, further enhances machinability and physical properties:
These properties make LMP brass a go-to material for applications requiring resilience, corrosion resistance, and ease of shaping.
