Here’s a performance comparison of stainless steel handles with other common materials (copper, aluminum alloy, plastic):
1. Corrosion Resistance
Stainless Steel: Exhibits superior corrosion resistance due to its chromium content (≥10.5%), forming a self-healing passive oxide layer. Ideal for humid or chemically aggressive environments (e.g., bathrooms, coastal areas) .
Copper: Naturally corrosion-resistant but prone to oxidation (tarnishing), requiring regular polishing to maintain aesthetics. Limited use in high-moisture areas .
Aluminum Alloy: Forms a thin oxide layer but is less durable than stainless steel in harsh conditions. Anodized coatings improve resistance but may wear over time .
Plastic: Non-corrosive but degrades under UV exposure and mechanical stress, leading to brittleness .
2. Strength and Durability
Stainless Steel: High tensile strength (500–2,000 MPa depending on grade) and scratch resistance. Withstands heavy use without deformation, making it suitable for high-traffic areas .
Copper: Softer and less durable than stainless steel, prone to denting. Often used for decorative purposes .
Aluminum Alloy: Lightweight but lower strength-to-weight ratio. Vulnerable to bending under heavy loads .
Plastic: Low structural integrity; cracks or warps under prolonged stress. Limited to low-impact applications .
3. Weight and Installation
Stainless Steel: Denser than aluminum but lighter than copper. Requires sturdy mounting due to its weight, ensuring long-term stability .
Copper: Heaviest among the four, increasing door stress over time. Requires reinforced hinges .
Aluminum Alloy: Lightest option, easy to install but may feel less premium .
Plastic: Extremely lightweight but prone to loosening or sagging .
4. Maintenance and Cost
Stainless Steel: Low maintenance (wipe with mild detergent) and long lifespan justify higher initial cost .
Copper: High upkeep (polishing to prevent patina) and expensive material cost .
Aluminum Alloy: Affordable and low-maintenance but less durable .
Plastic: Cheapest initially but frequent replacements increase long-term costs .
