Why we choose aluminum alloy to make aluminum case?

Aluminum cases come in various materials, including iron, wood, and plastic. However, aluminum alloy is often the preferred choice due to its numerous advantages. One of the main reasons for this is its excellent corrosion resistance, which makes it ideal for long-term use in different environments. Aluminum also has great thermal and electrical conductivity, making it a versatile material for a wide range of applications. Many modern aluminum boxes use an aluminum alloy frame, which not only provides structural strength but also offers a high load capacity, making it suitable for heavy-duty use. Another significant advantage of aluminum alloy is its strong moisture resistance. Even when exposed to environments with over 90% humidity for 48 hours, the contents inside the case remain unaffected. This makes aluminum cases highly reliable for storing sensitive items in challenging conditions. Additionally, aluminum is lightweight yet durable, making it easy to handle and transport without compromising on strength. It is also recyclable, which adds to its environmental benefits. When selecting an aluminum case, it's important to ensure that it is made from high-quality aluminum alloy to guarantee its performance and longevity. By choosing an aluminum case made from premium aluminum material, users can enjoy a combination of durability, protection, and efficiency—making it a smart investment for both industrial and personal use.

HK9 Glass Dome Lens

Dome lenses are hemispheres. The two optical surfaces are an equal thickness apart, creating a naturally strong shape that gets tougher under pressure. This makes dome windows ideal for underwater environments and in applications such as camera dome ports and submersible windows.
BK7 or K9L domes are used primarily in meteorology applications. BK7 offers excellent transmission from 300nm up to 2µm. BK7 is a relatively hard material, with excellent chemical durability.
UV fused silica domes ( JGS1 ): For applications operating in the deeper UV range, we offers a range of UV fused silica domes. Fused silica domes are commonly used in underwater applications at extremely high pressures.

Sapphire domes: For infrared applications we can provide sapphire domes. Sapphire is an extremely hard material with transmission of over 80% in the 2-5µm wavelength range. As with fused silica, sapphire is able to withstand extreme pressures, making it the perfect material for underwater camera and missile fairing applications.
