Ningbo Jiangbei XinYe Metal Works Co., Ltd. is a leading company in the metal works industry, specializing in a wide range of services including CNC machining, aluminum alloy forging, wax die stainless casting, extrusion and stamping, as well as anodizing and e-polish surface treatment. The company has been providing high-quality metal works solutions since its establishment in 1996.

Anodizing is a process that involves the application of an oxide layer to the surface of aluminum and aluminum alloys. This process provides several benefits, including increased corrosion resistance, improved appearance, and enhanced durability. The team at Ningbo Jiangbei XinYe Metal Works Co., Ltd. is highly experienced in anodizing 7075 aluminum, a popular aluminum alloy known for its high strength and resistance to stress corrosion cracking.

The anodizing process begins with the preparation of the aluminum surface, which involves thorough cleaning and degreasing to ensure optimal adhesion of the oxide layer. The aluminum is then immersed in an electrolyte solution, with the aluminum acting as the anode. An electric current is passed through the solution, causing oxygen ions to bond with the aluminum surface and form the desired oxide layer. This layer can then be further processed to achieve specific finishes and appearances.

One of the main advantages of anodizing 7075 aluminum is the enhanced corrosion resistance it provides. The oxide layer formed during the anodizing process acts as a barrier, protecting the underlying aluminum from environmental factors such as moisture and chemicals. This makes anodized 7075 aluminum an ideal choice for applications that require long-term durability in harsh conditions, such as aerospace components, automotive parts, and outdoor equipment.

In addition to improved corrosion resistance, anodizing also offers aesthetic benefits. The process can be used to create a range of colored finishes, from natural metallic tones to vibrant hues, depending on the desired application. This makes anodized 7075 aluminum a versatile choice for architectural, decorative, and branding purposes, allowing for custom designs and branding opportunities.

Furthermore, anodizing enhances the mechanical properties of 7075 aluminum, including its hardness and wear resistance. This can be particularly advantageous in applications where the aluminum will be subject to significant wear and tear, such as in industrial machinery and consumer electronics. The increased surface hardness provided by anodizing can extend the lifespan of the aluminum components, reducing the need for maintenance and replacement.

The team at Ningbo Jiangbei XinYe Metal Works Co., Ltd. is committed to delivering superior anodizing results for 7075 aluminum, leveraging their extensive expertise and advanced capabilities in surface treatment. With a strong focus on precision and quality, the company ensures that each anodized component meets the highest standards for performance and appearance.
