Common Material Classification & Introduction
1. Gray Cast Iron HT200/HT250 (Mainstream General Type)
Features: Moderate hardness, easy processing, good shock absorption and stable dimension.Advantages: High cost performance, low noise, suitable for mass production.Application: Fans, water pumps, air compressors, agricultural machinery and other general machinery.Note: Weak impact resistance; anti-rust treatment required in humid environments.
2. 45# Carbon Steel (Precision Reinforced Type)
Features: High strength and good toughness; wear resistance can be improved by quenching; high precision.Advantages: Strong load capacity, not easy to deform, suitable for medium-high speed and medium-heavy load.Application: Machine tools, printing, packaging and other industrial transmission equipment.Note: Prone to rust; surface anti-rust treatment is required.
3. Aluminum Alloy 6061/6063 (Lightweight Type)
Features: Light weight, low inertia, available for anodizing, high precision.Advantages: Stable high-speed operation, sensitive start-up, oxidation resistance.Application: Small automation equipment, office equipment, high-speed light-load occasions.Note: Not suitable for heavy load, high torque and impact working conditions.
4. Stainless Steel 304/316 (Anti-Corrosion Special Type)
Features: Rust-proof, corrosion and acid-alkali resistant, high sanitary standard.Advantages: Maintenance-free, rustproof, suitable for harsh environments.Application: Food, medical, chemical and seaside outdoor equipment.Note: High cost, only applicable for light and medium load.
5. Ductile Iron QT500/QT600 (High-Strength Heavy-Duty Type)
Features: Much higher toughness and tensile strength than ordinary cast iron, wear and impact resistant.Advantages: Large load capacity, vibration resistance, stable operation under heavy load.Application: Mining, heavy industry, heavy-duty conveying and other severe working conditions.Note: High cost; aging treatment required to prevent processing deformation.
FAQ：
Q: How to solve loud noise and abnormal sound during pulley operation?
A:
- There are burrs and uneven wear on the groove surface; just polish it smooth.
- The belt is loose or aged; adjust the tension or replace the belt.
- The two pulleys are installed eccentrically causing heavy vibration; recalibrate the alignment.
Q: How to prevent pulleys from getting rusty after a period of use?A:
- Cast iron and carbon steel pulleys should be treated with galvanizing, blackening or anti-rust oil.
- Avoid storing or using them in humid and rainy environments.
- Regularly clean surface dust and water stains for daily maintenance.
