Why marine plugs are made of brass, for example as follows
1. Brass in alloy copper:
Brass has the advantages of excellent machining performance, good electrical performance, and can be crimped. The disadvantage is that the fatigue limit is very low, and it is not suitable for elastic components. It is often used to make pins, wire spring jack bodies, and crown spring jack bodies. H62 and HPb59-1 are commonly used in brass.
2. Beryllium bronze in alloy copper:
The advantages of beryllium bronze are excellent elasticity, high working temperature (150 ℃), good electrical conductivity, high fatigue limit, and good electrical performance (22% copper content), but the disadvantages are poor crimpability, high tooling costs, and relatively expensive finished products. , and need to undergo heat treatment when used. Beryllium bronze mainly uses QBe2, which is mainly used in cantilever beam type (split type) jacks with diameter less than 0.76, wire spring wire of wire spring jacks and reeds of crown spring jacks.
3. Tin phosphor bronze in alloy copper:
The advantage of tin phosphor bronze is that it is easy to process and form, does not require heat treatment, the price is cheaper than that of beryllium bronze, and the elasticity is good but lower than that of beryllium bronze. Tin phosphor bronze mainly uses QSn6.5-0.1, which is mainly used in cantilever beam type (split type) jacks with diameter greater than 0.76, wire spring wire of wire spring jacks and reeds of crown spring jacks.
