3000 Aluminum: 3005 and 3105 Alloy

Publish: Modify: Oct 31, 2024Author: From:  Haomei

Commonly used grades of 3000 series aluminum are 3003, 3004, 3005, 3104, 3105, etc. How much do you know about aluminum 3005 and 3105? A highlight of their mechanical properties. Learn more.

3000 Aluminum is the most widely used rust-proof aluminum. It uses manganese as the main alloying element with a content of about 1.0-1.5. It is slightly lighter and more expensive than 1 series. It cannot be strengthened by heat treatment, but has good plasticity after cold working and annealing. Commonly used grades are 3003 aluminum alloy, 3004, 3005, 3104, 3105, etc.

The mechanical properties of aluminium 3005 depend on the specific alloy temper and heat treatment conditions. The following are the mechanical properties of 3005 aluminum alloy under normal circumstances:

1. Tensile strength: Generally, the tensile strength of 3005 aluminum alloy is between 120-205 MPa. This is the ability of the alloy to resist damage under tensile stress, which can reflect the strength level of the alloy.

2. Yield strength: The yield strength of 3005 aluminum alloy is generally between 70-140 MPa. Yield strength refers to the maximum stress level that the material withstands when it undergoes plastic deformation.

3. Elongation: The elongation of 3005 aluminum alloy is generally between 5% and 30%. Elongation refers to the amount of plastic deformation that a material can produce before tensile fracture, reflecting the ductility of the material.

4. Hardness: The hardness of 3005 aluminum alloy depends on the state of the alloy and the heat treatment. The general hardness value is between 40-70 HB. Hardness refers to the ability of the material to resist local indentation, which is usually used to measure the hardness level of the material.

Alloy 3105 is an aluminum alloy with good corrosion resistance and machinability. The following are its main properties:

1. Strength and hardness: It has medium strength and hardness, with a hardness of about HB45-55 and a tensile strength of 95-140MPa.

2. Corrosion resistance: 3105 aluminum has good resistance to atmospheric and seawater corrosion, and can maintain good performance for a long time in many corrosive media.

3. Machinability: It has good adaptability to machining, riveting, deep drawing, welding and cutting processes, and can be processed into a variety of complex shapes.

4. Welding performance: It has good welding performance and can be welded by conventional TIG, MIG and arc welding.

5. Thermal conductivity: It has good thermal conductivity and can be used in applications that require high heat dissipation performance, such as making radiators.

6. Electrical properties: Alloy 3105 has excellent electrical properties and can be used to make electrical wires and cables for electrical, electrification and rail transportation equipment.
