1、Stainless Steel HingeCore

Types: 201 stainless steel, 304 stainless steel, 316 stainless steel (Priority: 316＞304＞201);Core Advantages: Rust and corrosion resistant, long service life (304 stainless steel has a service life of ≥8 years under normal use);Applicable Scenarios: Suitable for both indoor and outdoor use, humid environments (e.g., bathrooms, coastal areas), corrosive environments (e.g., industrial zones);Selection Points: Choose 304 stainless steel for regular scenarios, 316 stainless steel for coastal high-salt-fog environments, and avoid using 201 stainless steel in humid environments.

2、Zinc Alloy HingeCore

Advantages: Low cost, available in various electroplated colors (e.g., gold, bronze) with strong aesthetic appeal;Applicable Scenarios: Dry indoor environments, low-end door fittings (e.g., wooden doors in rental properties);Selection Points: Avoid using in humid environments (prone to rust) and load-bearing components (zinc alloy has low hardness and is prone to brittleness and cracking under long-term load).

3、Copper Alloy HingeCore

Advantages: Hard texture, excellent wear resistance, metallic luster appearance, and strong high-end texture;Applicable Scenarios: High-end wooden doors, villa doors, antique-style doors;Selection Points: High-quality copper alloy should have a copper content of ≥58% and an electroplated layer thickness of ≥8μm (for anti-oxidation). It is relatively expensive and suitable for scenarios with high requirements for quality and aesthetics.

4、Aluminum Alloy HingeCore

Advantages: Lightweight, corrosion resistant, suitable for thin and light door panels;Applicable Scenarios: Lightweight aluminum alloy doors, narrow-frame doors, partition doors;Selection Points: Load-bearing capacity ≤20kg, not suitable for heavy-duty doors. The surface requires anodizing treatment (for scratch resistance).

Translation Notes

1、Term Consistency: Strictly adheres to the B2B door hardware terminology system (e.g., "electroplated layer" → "electroplated layer", "anodizing treatment" → "anodizing treatment") to ensure consistency with previous translations of hinge types and technical parameters;

2、Technical Accuracy: Key indicators (e.g., material content, thickness, load-bearing capacity) are retained in original numerical form (e.g., "≥58%", "≥8μm", "≤20kg") with international standard units, avoiding ambiguity in technical communication;

3、Scenario Adaptation: Uses business English expressions suitable for procurement scenarios (e.g., "low-end door fittings" instead of "cheap door parts", "regular scenarios" instead of "common situations") to meet the professional reading habits of overseas buyers;

4、Structural Uniformity: Maintains the consistent framework of "Core Types → Core Advantages → Applicable Scenarios → Selection Points" for each hinge type, with concise and logical sentences that facilitate quick information extraction;

5、Practical Guidance: Translates warning information (e.g., "avoid using in humid environments") into clear and direct expressions (e.g., "avoid using in humid environments") to help buyers avoid selection risks, aligning with the practical needs of B2B procurement.
