There are many types of metal alloys. You should know that Zamak 3 is a common alloy. The composition of this alloy includes zinc, lead and other metals, as well as small amounts of aluminum. Copper is added to Zamak 3 to improve its strength and hardness.
The alloy is used for many things including die-casting parts and making machine parts. In the past, this metal was the most common metal alloy in the world. Now, it’s being replaced with Zamak 5. This is a zinc alloy with copper and lead.
In some places, people refer to this alloy as Zamak 3B. When zamak die casting people talk about die-cast aluminum, they are actually talking about Zamak 5.
It has less dimensional accuracy than Zamak 3. This means that it has less precision when it comes to creating the parts.
This alloy also doesn’t have very good properties when it comes to bending and machining. In the past, this alloy was very common. Today, it is being replaced by Zamak 3.
