4047 Aluminum is an alloy comprising small portions of silicon, copper, iron, magnesium, and zinc. These metal portions comprise 15% of the total proportion of the aluminum sheet. The rest, 85%, is aluminum. It does not require any heat treatment.

You can use this alloy to make 4047 aluminum sheet metal.

The four-digits “4047” serves an important purpose in 4047 aluminum sheets. The

  • The first digit, “4,” represents the classification of alloy
  • The second digit, “0,” represents any alloy modifications
  • The last two digits, “47,” represents the specific content label

The silicone content is comparatively more in 4047 aluminum sheets. This adds up unique properties to the end material.

Advantages of 4047 Aluminum Sheet

A plethora of advantages contribute to the real worth of 4047 aluminum sheets. Down below, you will find insights on key benefits.

· Excellent Corrosion Resistance

Corrosion refers to the undesirable phenomenon when it comes to metal. No one likes the deterioration that their metal will face with time. But you don’t need to worry when you have 4047 aluminum sheets. It offers great resistance to rust and corrosion. You can use it anywhere without worrying about the adverse impact of weathering chemicals.

· Low Melting Point

Melting point refers to a stage at which a material changes its state from solid form to liquid form. This happens at atmospheric pressure.

The term lower melting point refers to the ability of the metal to fuse quickly at lower temperatures. You can experience a narrow freezing range with a 4047 aluminum sheet.

· High Fluidity

The term fluidity refers to the ability of a metal to flow. 4047 aluminum sheets possess high fluidity. This feature enables the usage of 4047 aluminum sheets in casting applications. Because high fluidity allows you to experience the complete filling of the mold cavity and prevents casting defects such as misrun.

· High Electrical and Thermal Conductivity

4047 aluminum sheets help you enjoy higher thermal and electrical conductivity. The metal fusion ability in the structure of 4047 aluminum allows it to conduct a speedily flow of electrons. You can also experience a quick flow of heat throughout the metal at higher temperatures.

· Lightweight

The lightweight is another worth considered feature of the 4047 aluminum sheet. It offers low density. You can reap the benefits of its light when you need higher efficiency and effectiveness. In moving such a component, you don’t need a bigger force.

· High Strength-to-Weight Ratio

It is a key benefit of the 4047 aluminum sheet. This reflects you can enjoy higher strength at a lower weight. This feature is desirable when you need to offer resistance against breakage. With 4047 Aluminum, you can experience higher impact resistance.
