What are the advantages and disadvantages of different raw materials of carabiners?
| Carabiners | Advantage | Disadvantage |
| AluminumAlloy | 1. Lightweight(easy to carry) 2. Oxidation (anti-corrosion & anti-rust & strongcolor adhesion) 3. Strong plasticity(can be processed into variousshapes) 4. Wide range of uses(eg. outdoor sports, sportinggoods, pet accessories, EDC) Mainly occupies themarket oflightweight travel products | 1. Weak load-bearing capacity |
| Stainless Steel | 1.Strong durability and load-bearing capacity (egmountaineering) | 1. Easy to rust (easy to oxidize andrust when exposed to water ohumid environment, affectinguse and not durable) 2. Not easy to carry (inconvenientfor daily use) |
| lron | 1. Strong corrosion resistance 2. High strength resistance (not affected byenvironment or temperature) | 1. Not easy to carry (the weight isnot light enough for daily use) 2. High price (high cost) |
| Zinc Alloy | 1. Suitable for decorative purposes (key chains,small accessories) | 1. Not durable |
| Summary | a. Iron: Stronger than aluminum alloy, but heavy and prone to rust, the heayiest one. b. Stainless steel: Stronger and more durable than aluminum alloy, but heavy. c. Zinc alloy: Heavier andless durable than aluminum alloy | |
