Materials and Strength:
Aluminum alloy: relatively strong, wear-resistant and corrosion-resistant, suitable for use in places where high strength is required, such as industrial equipment and outdoor environments.
PVC/PUR plastic: relatively light, but not as durable as aluminum alloy. PVC is often used in ordinary household appliances, while PUR is more wear-resistant, but not as strong as aluminum alloy overall.
Weight:
Aluminum alloy: relatively heavy, but can withstand greater pressure.
PVC/PUR plastic: relatively light, suitable for places that do not need to be too heavy.
Cost:
Aluminum alloy: more expensive, suitable for high-end products.
PVC/PUR plastic: cheap, suitable for occasions with limited budgets.
Protection:
Aluminum alloy: waterproof, dustproof, and corrosion-resistant, suitable for harsh environments.
PVC/PUR plastic: average protection, suitable for ordinary environments.
Summary
Aluminum alloy connectors are suitable for occasions that require high strength and durability, such as industrial equipment and outdoor equipment.
PVC/PUR plastic connectors are suitable for ordinary household appliances, low-cost equipment, and less demanding environments.
