Drop Forging for Aluminum Alloys

Drop Forging is a metal forming technology that hammers the metal between the dies. This kind of metal forming process is suitable for mass production of metal components. Before drop forging, half of the die is attached to the hammer, and half to the anvil. Then hot metal is placed in the lower half of the die, then pressed by high pressured to fill the die cavity. In this step, excess metal material is squeezed out between the dies, which is called flash. Next, remove the excess flash under the workforce of trimming die to achieve net shape products.

By drop forging, different sizes of components can be produced, and it can produce near net shapes that require only a small amount of machining, or even net shape without secondary machining. It is quite economic for large production runs.
Typical metals can be drop forged include: steel alloys, copper alloys and aluminum alloys, among which aluminum alloys are the lightest. So aluminum forgings are gradually replacing steel forgings, especially for automotive and aerospace industries. Customer may doubt the section of drop forging for aluminum alloys, as the professional drop forging company, here we would like to introduce in detail.

First of all, you should understand the charteristics of aluminum alloys. Aluminum is a metal similar to steel, brass, copper, zinc, lead or titanium. It can be melted, cast, forged and machined in a similar way to these metals and conducts electric currents. Aluminum is a very light metal with a specific weight of 2.7 g/cm3, about a third of that of steel. This cuts the costs of manufacturing with aluminum forgings. Again, its use in vehicles reduces dead-weight and energy consumption while increasing load capacity. This also reduces noise and improves comfort levels.

Secondly, why aluminum alloys can be drop forged? We all know that aluminum alloy is softer than other metals, which enables aluminum alloys easliy get deformed under the pressure of forging dies. Drop Forging of aluminum alloys can creat lots of forged aluminum components for a variety of applications, such as automotive, motorcycle, aerospace, pipe fittings, etc. 

Thirdly, which types of aluminum alloys can be drop forged? Lots of aluminum alloys exsit in the world, but it does not mean all aluminum alloys can be used to produce parts by drop forging. Generally, aluminum alloys can be divided into cast aluminum and forged aluminum. Cast aluminum alloys are like: A356, A380, etc. While forged aluminum alloys include: 6061, 6063, 6082, 7075, etc. Besides, after drop forging, the forged aluminum blanks will be proceeded to heat treatment process.

As the leading drop forging supplier in China, CFS Forge has been in drop forging industry for aluminum alloys for more than 20 years. With the efforts of all staff, we have rich experience in aluminum drop forging and machining. Would like to source forged aluminum parts from China company? Pls do not hesistate to contact us!
