An aluminum flange is a commonly used pipe fitting designed to connect and seal different pipelines or equipment interfaces. It is made from aluminum materials, including 6061 aluminum alloy and 5083 aluminum alloy, which offer advantages such as lightweight, corrosion resistance, and high strength. Aluminum flanges are widely used in various industries, including shipbuilding, chemical processing, petroleum, natural gas, pharmaceuticals, and food processing.

The 6061-T6 anodized aluminum flange is typically connected by two facing flanges fastened with bolts. It can be welded, threaded, or flange-connected. Aluminum flanges are available in different specifications and pressure ratings to meet the requirements of various projects and pipeline applications.

As a reliable pipeline connection accessory, an aluminum alloy flange provides numerous benefits, making it suitable for a variety of industrial and commercial applications. When selecting an aluminum flange, factors such as pipeline pressure, temperature requirements, and the characteristics of the medium should be considered to ensure a secure and reliable connection.

6061-T6 Aluminum Alloy Overview

6061-T6 is a heat-treated, high-strength aluminum alloy (MC Aluminum product) primarily composed of magnesium (Mg) and silicon (Si). It offers excellent strength, corrosion resistance, weldability, and machining performance. The T6 designation indicates that the alloy has undergone solution heat treatment followed by artificial aging, achieving maximum strength.
