Properties of Aluminum

Light Weight-Durability-Malleability-Lower Material Hardness-No Magnetism-Non-Lustrous

Excellent Corrosion Resistance-Greater Formability

Aluminum offers an excellent strength-to-weight ratio and sheer variety that enables aluminum to react with other elements to form alloys.

These alloys are also mostly acceptable for CNC machining projects.

Aluminum alloys in comparison to other lightweight metals (such as magnesium and titanium alloys) are preferred due to obvious reasons that are discussed ahead.

These benefits have made aluminum parts common across all industries, though they are particularly favored in the automotive, aerospace, healthcare, and consumer electronics sectors.

Benefits of CNC Machined Aluminum Parts

Aluminum offers an added advantage for CNC machining.

Its properties help to optimize precision processing that ultimately results in optimal part fabrication.

Key benefits of CNC machined aluminum parts include

Excellent Strength-to-Weight Ratio-Excellent Machinability-Custom Finishing-Resistant to Low

Temperatures-Environment Friendly-Corrosion Resistant-Tremendous Electrical Conductivity

Applications of CNC Machined Aluminum Parts in Different

Industries

Aluminum CNC machined grades are used across different industries for manufacturing a huge variety of parts.

Some of the industries that use aluminum due to its added advantages are discussed below

Aluminum is preferred in many industries due to its tremendous machining friendly properties.

Commonly Used Aluminum Grades in CNC Machining

Aluminum has numerous grades.

Each grade has its separate features and applications.

Selecting an optimal grade depends on your intended use as per your part requirements.

You can categorize each grade that fulfills specific needs.

It will help you to choose the best grade according to

definite properties, geometry, and budget.

Aluminum 6061

Aluminum 6061 is a precipitation-hardened aluminum alloy.

It consists of magnesium and silicon as major alloying elements.

It is amongst the most common aluminum

alloys for machining in the 6xxx series.

Properties

Its properties are good corrosion resistance, excellent weldability, medium fatigue strength, etc.

Parts manufactured using aluminum 6061 are

Marine Frames-Aircraft and Truck Frames-Electronic Parts-Truck Bodies-Valves-Furniture - Fasteners-Heat Exchangers

Aluminum 7075

Aluminum 7075 is a valuable grade used for highly stressed structural applications.

Its primary alloying element is zinc and also contain 5.6–6.1% zinc, 2.1–2.5% magnesium, 1.2– 1.6% copper, and less than a half percent of silicon, iron, manganese, titanium, chromium, and other metals. It also offers excellent mechanical properties like

Good Ductility

High Strength

Toughness

Good Fatigue Resistance

Products manufactured aluminum 7075 are

Gears

Transport Vehicle Parts

Bicycles Fuse Parts

Structural Components

Weapons

Bows

Aircraft Parts

Aluminum 2024

Aluminum 2024 is one of the most common aluminum alloys for machining from the 2xxx group.

It contains copper as the primary alloying element.

It is stronger than 6061 but less versatile.

This aluminum and copper alloyed material is used in manufacturing such parts that require a high strength-to-weight ratio and good fatigue resistance.

Aluminum 2024 offers properties like

High Strength

Good Workability

Good Strain Resistance

Fatigue Resistance

Parts manufactured using Aluminum 2024 are

Car Parts

Aircraft Structures

Wings

Fuselage

Transport Vehicle Parts

Aluminum 6082

Aluminum 6082 is known as structural alloy.

It is made through extrusion and rolling.

It is very popular in the 6000 series.

It falls in the wrought aluminum-magnesium-silicon family and has the highest strength as compared to other alloys of its series.

It contains a predominant quantity of manganese which modulates its grain structure. This grain structure makes aluminum 6082 stronger.

But creating thin walled, complex geometrical shapes using 6082 alloy is hard. Because the resulting surface quality is not smoother than other alloys in 6000 series.

Aluminum 6082 offers excellent

Corrosion Resistance

High Machinability

Fatigue Resistance

Good Ductility

Fatigue Resistance

It is mostly used in construction and automotive industries for creating parts like trusses, cranes, bridges, trusses, milk churns, ore skips etc.
