In reality, there are various materials used for housing aluminum cases, such as iron, wood, and plastic. However, aluminum alloy is often the preferred choice due to its unique advantages:
1. Aluminum has excellent corrosion resistance, good thermal and electrical conductivity. Most modern aluminum cases use an aluminum alloy frame, which also offers a high load capacity, making it ideal for heavy-duty applications.
2. The moisture-proof performance of aluminum alloy is outstanding. Even when exposed to environments with over 90% humidity for 48 hours, the contents inside the case remain unaffected, ensuring long-term protection.
Moreover, aluminum is lightweight yet durable, making it easy to handle and transport. It's also highly recyclable, which makes it an environmentally friendly option. These combined benefits make aluminum alloy the best material for constructing reliable and long-lasting aluminum cases.
When selecting an aluminum case, it’s important to ensure that it is made from high-quality aluminum alloy. This guarantees both durability and performance, ensuring your equipment or products are well-protected in any environment.
Plane ruled gratings are characterized by a superior efficiency at their design wavelength compared with holographic gratings. Plane Ruled gratings comprise the majority of diffraction gratings used in spectroscopic instrumentation and are especially useful in systems requiring high resolution.Â
China star optics can provide customers with a variety of replicated grating products such as diffraction gratings, reflective gratings,holographic gratings,concave gratings etc. to meet different needs. Maximum ruled area is up to 300 x 300 mm for plane ruled diffraction gratings. For replicated diffraction and transmission gratings the ruling density can be from 20 grooves per millimeter to 2400 grooves per millimeter, wavelength from 0.2 micron to 25 microns.Â
