5. FAQ
Q: Can I know what is copper alloy material ?
A: The most common type is 65Mn spring steel,65Mn is the most widely used material for sealing component skeletons, especially in heavy machinery like excavators, due to its excellent comprehensive performance and cost-effectiveness.
Key Performance Characteristics:
- High Elasticity and Strength: As a spring steel, its core property is high elastic limit and yield strength. This allows the metal skeleton to provide a strong, consistent supporting force to the rubber or polymer seal, preventing deformation under high pressure.
- Good Toughness: It possesses good toughness and can withstand impact and vibration, which are common in construction equipment, without fracturing.
- Moderate Hardness: After heat treatment (quenching and tempering), it achieves an optimal balance of hardness and elasticity, providing wear resistance without becoming brittle.
- Cost-Effective: As we know, if a material has a high cost, it can have a significant impact on its widespread use.Compared to stainless steels and special alloys, 65Mn is significantly more economical, making it the ideal choice for high-volume industrial applications where extreme corrosion resistance is not the primary concern.
Q:The material of the ring seal is a mixture of PTFE and fiberglass. What are its advantages?
A: the PTFE and fiberglass mixture creates a synergistic material that is far more capable than either component alone, offering a unique combination of strength, durability, and resistance to extreme environments.
I can explain it to you briefly in a few points, and you will understand why the prices of products of the same size vary so much.
- Combined Advantage: It has the advantages of both materials.The surface is extremely easy to clean, prevents material buildup, and allows for the easy release of substances. This is crucial for applications like food processing belts, release sheets, and architectural membranes where dirt and snow need to slide off.
- This material can withstand high temperatures and operate in lower environments, greatly improving the working life of the machine.
