Frequently Asked Questions (FAQ)

• Why consider mechanical properties when choosing Cavity & Casing materials?

• Mechanical properties like strength, stiffness, impact resistance, and wear resistance determine the durability and reliability of Cavity & Casing in practical use. Different application scenarios have different requirements for these properties; for example, industrial equipment might require higher wear resistance, while aerospace might focus more on strength and lightweight.

• Which metal material should be chosen for Cavity & Casing in high-temperature environments?

• In high-temperature environments, superalloys like nickel-based or cobalt-based alloys are recommended due to their ability to maintain high strength and corrosion resistance at high temperatures. Additionally, stainless steel (especially type 316) is often used where some heat resistance is needed.

• How can surface treatment enhance the performance of Cavity & Casing?

• Surface treatments like anodizing for metals, electroplating, or coating and laminating for plastics can significantly improve corrosion resistance, wear resistance, aesthetics, and thermal management. For instance, anodizing aluminum alloys increases their corrosion resistance and hardness, while texturing plastics can improve grip and appearance.

• Why is stainless steel chosen as a casing material for medical devices?

• Stainless steel is selected for medical devices because of its excellent biocompatibility, corrosion resistance, and ease of sterilization. These properties ensure safety and durability in medical environments, particularly 316L stainless steel, which, due to its low carbon content, further enhances corrosion resistance.
