What Are Main Alloys of 1/4 Aluminum Sheet 4x8

4X8 Aluminum Sheet Metal can also be called 4 by 8 sheet of aluminum. The “4 x 8” generally refers to the ratio of the width to length of the aluminum sheet. The “4 x 8” generally refers to the ratio of the width to length of the aluminum sheet.

4’ represent 4 foot and 8’ represent 8 foot. The size in mm is 1219 mm x 2438mm. 1/4 refers to 0.25 inch, which is 6.35 mm. 1/4 aluminum sheet 4x8 is 6.35 mm thick, 1219 mm wide and 2438 mm long. It is a popular specification. The main alloys include 6061 and 5052.

The main alloy elements in 6061 aluminum plate are magnesium and silicon, which have medium strength, good corrosion resistance, weldability and good oxidation effect. It is widely used in various industrial structural parts that require certain strength and high corrosion resistance. The common tempers are O, T4, T6, T651 and H112.

6061 aluminum sheet has many advantages such as good anodizing effect, small deformation after processing, uniform quenching, etc., and is widely used in molds, automobiles, machining, 3C products and other fields. Its common temper is T6. The hardness of 6061T6 aluminum plate can be around 95-100HB.

6061-T6 aluminum sheet is a medium hardness aluminum plate with good hardness and reasonable price. The aluminum plate has the characteristics of high hardness, good cutting performance and excellent welding performance. It is suitable for various processing such as lathe turning, milling and grinding. It is often used in mechanical parts, auto parts, mold manufacturing and other machining industries that require a certain strength.

The 5052 alloy aluminum plate belongs to the aluminum-magnesium alloy, in which the magnesium alloy content is close to 2.5%, which belongs to the medium-hardness alloy. Its common tempers are H32 and O. In the H32 state, the Webster hardness is 10-11 degrees, and the 0 state is 7-8 degrees. For the thick 5052 aluminum plate, we choose O-temper aluminum sheet to bend. 5052-h32 aluminum can be bent in the state of thin aluminum sheets.

1/4 aluminum sheet 4x8 is very easy to cut, but for 6061 and 5052 aluminum sheet, the thicker aluminum sheet is also often used. Sometimes, the thickness is more than 10mm, even up to 300mm. How can the ultra-thick 6061 aluminum plate be cut? At this time, we need professional sawing equipment. Usually, we will choose a sawing machine (circular sawing machine or metal band sawing machine) for 6061 or 5052 aluminum sheet.

Sawing is different from shearing. Sawing needs to reserve a margin. For example, the loss of sawing gap should also be calculated. At the same time, sawing is different from shearing precision. Usually, there will be a margin when cutting the 6061 aluminum plate. Generally, we are used to controlling the margin at 3-5 mm.
