Aluminum is the Best Alloy for Casting

Posted by Metalworkinchina on September 5th, 2019

Fabricated metal processes include various steps such as cutting, bending, forging, welding and machining are used to shape individual metal parts, while other processes such as assembling and welding are used to join separate parts together. Establishments in this manufacturing sector may use one of these processes or combination of these processes.

The manufacturing performed in the subsector fabricated metal product manufacturing begins with the shapes of manufactured metals. Metal fabrication creates the metal structure by cutting, bending and assembling processes. This process involves the creation of parts, machines and structures from various raw materials. Typically, a fabrication shop does a job bidding, are usually based on engineering drawings, and if contract is awarded, builds the product.

Usually, metal fabrication starts with drawings with precise specifications and dimensions. These shops are employed by contractors, VARs and OEMs. Typical projects include structural frames for buildings, loose parts, heavy equipment, and stairs and hand railings.

Processes

• Cutting- Done by shearing, sawing or chiseling
• Bending- Done by hammering or via tube benders, press brakes and similar tools
• Assembling- Done by welding binding with adhesives, threaded fasteners, riveting or bending in the form of crimped seams

Die casting is the metal casting process that can mold cavity under high pressure. Most of the die castings are come up with non-ferrous metals, such as copper, zinc, lead, aluminum, magnesium, pewter and tin based alloys.

Aluminum has high dimensional stability for thin walls and complex shapes and can easily be plated. An aluminum die casting is light in weight and is also economical for smaller parts. It is able to withstand the highest operating temperatures of all die cast metal alloys.

Aluminum Die Casting Characteristics

• Light weight
• High electrical conductivity
• High operating temperatures
• Good strength and hardness
• Corrosion resistance outstanding
• Excellent RFI and EMI shielding properties
• Excellent thermal conductivity
• Good finishing characteristics
• Full recyclability

Aluminum Die Casting Applications

o Improves automation fuel efficiency by leading to weight saving requirements
o Widely used in networking and infrastructure equipment in the telecom and computing industries
o Provides EMI/RFI shielding, rigidity and durability with minimal weight in handheld devices
o Ideal for electronic connectors and housings, all because of aluminum’s excellent electrical performance and shielding properties, even in high temperature environments

It is proven that aluminum die casting is beneficial to industrial products. More sophisticated machines are now used to have consistent quality control with the modern technology.
