Introduction

The 0.6–0.8 mm 3105 aluminum sheet with scratch-resistant coating is currently the most popular mid-to-high-end specification worldwide for washing machine side panels (lateral covers), front/back structural panels and outer housing components.

Compared to 3003 (softer) or 5052 (stronger but more expensive), 3105 provides the optimal balance for modern appliance exteriors:

~20% higher yield strength than 3003 → excellent dent & scratch resistance in daily use

Perfect flatness & coating adhesion for high-speed roll-forming & punching

Cost-effective yet premium appearance with scratch-resistant & fingerprint-proof finish

Ideal for humid laundry environments with frequent touching & cleaning

Coating system

25–30 μm high-durability polyester (PE) base + scratch-resistant nano topcoat,Optional antimicrobial additive,Standard colors: RAL 9010 pure white, RAL 7035 light gray, metallic silver,Warranty: 25 years indoor color stability, gloss retention & scratch resistance

FAQ (USA/Europe/Asia/Middle East Buyers)

Q1: Why choose 3105 over 3003 for washing machine panels?

A: 3105 has ~20% higher yield strength → better dent & scratch resistance for high-touch side panels, while remaining much easier to form & cheaper than 5052. It is the industry sweet spot for premium appliances.

Q2: How effective is the scratch-resistant & fingerprint-proof coating?

A: Nano topcoat hardness 2H–3H; fingerprints & light scratches wipe off with a dry microfiber cloth in seconds. Real touch-test samples & abrasion test reports (ASTM D4060) provided.

Q3: Can the sheet be embossed or pre-punched for better rigidity / ventilation?

A: Yes — 3105 is very suitable for diamond / stucco embossing or pre-punching ventilation/louver holes. We supply embossed samples & forming suggestions to avoid cracking.

Q4: Minimum order quantity & lead time for custom colors?

A: MOQ 5–10 tons (depending on color); standard white/gray 15–25 days; custom RAL match 25–35 days. Sample coils (small roll) free with freight collect.

Q5: How does 3105 perform in high-humidity / coastal markets (e.g., Southeast Asia, Middle East)?

A: Excellent — PE coated 3105 passes 2000–3000 h salt-spray; no white rust or pitting in 90%+ humidity laundry rooms. We provide humidity chamber & salt-spray test data.

Q6: Is the coating detergent & cleaning agent resistant?

A: Yes — passes resistance to common laundry detergents, bleach & alkaline cleaners (tested per ASTM D1308). No discoloration or peeling after repeated cleaning cycles.
