What are the differences between 7075 and 6061 aluminum alloys

1. Different ingredients

The 7075 series mainly uses zinc as the main alloy, and the composition ratio reaches 6%. The 6061 series mainly uses magnesium and silicon as the main alloys, and the total composition ratio is low.

2. Different intensity

In terms of strength, 7075 is stronger, no less than steel, but only a little stronger than 6061.

3. The price is different

7075 is the lightest and strongest aluminum, and the price is super expensive, while 6061 is the most common aluminum, light, strong, and affordable.

4. Different practicability

7075 contains a high proportion of other metals, so welding, processing are more difficult, its proportion is higher, so it is generally not used as a frame material. 6061 Due to the low proportion of other metals, it can increase its strength and reduce its wind resistance through special shape and various treatments, and even reduce the weight by three times pumping the tube. On the whole, 6061 is a better material.

Second, the difference between zinc alloy and aluminum alloy

1. Different raw materials

Zinc alloy is an alloy with other elements added on the basis of zinc, and the commonly added alloy elements are low-temperature zinc alloys such as aluminum, copper, magnesium, cadmium, lead and titanium. Zinc alloys are manufactured by melting and become materials in die casting and stamping processes. Aluminum alloy is a general term for aluminum-based alloys, the main alloying elements are copper, silicon, magnesium, zinc, manganese, secondary alloying elements are nickel, iron, titanium, chromium, lithium and so on.

2, different scope of application

Zinc alloy can be divided into cast zinc alloy and deformed zinc alloy according to the manufacturing process, which can be used for die-casting meters, galvanized corrosion prevention on the surface of automobile parts shell poles, and galvanized treatment of boiler water wall pipes to improve high temperature corrosion resistance. Aluminum alloy is the most widely used non-ferrous structural material in industry, widely used in aviation, aerospace, automotive machinery manufacturing, shipbuilding, chemical industry and so on.

3, the soup temperature is different during processing

Zinc alloy at more than 400 degrees; Aluminum alloy more than 700 degrees.

4, processing equipment is different

Although both are called die casting machines, they can not be universal at all.
