🔄316 Stainless Steel vs. Aluminum Alloy ATC
Comparison Items: FUDJUR FJ5852 (316 Stainless Steel) Ordinary Aluminum Alloy ATC
Material: 316 Stainless Steel, 6061/7075 Aluminum Alloy
Braking Force: Stronger, Stable Coefficient of Friction: Average
Abrasion Resistance: Excellent, withstands thousands of abrasions: Good, but easily worn
Corrosion Resistance: Excellent, resistant to seawater/acids and alkalis: Average, easily corroded after anodized layer wears off
Heat Dissipation: Good, Excellent (aluminum alloy conducts heat quickly)
Weight: 78g, usually 50-70g
Service Life: Extremely long, heirloom-worthy: Relatively long, but needs replacement after wear
🧗♂️Usage Tips
Single Rope Adescent: Rope passes through one channel
Hold the brake end to control speed
Suitable for vertical descents
Double Rope Adescent: Two ropes pass through two channels respectively
Suitable for long-distance descents, easy to pull the rope
Commonly used in lead climbing
Top Rope Belay: Rope passes through the ATC and connects to the belayer
Smooth rope reeling, reliable braking
Suitable for climbing gyms or outdoor top rope belay
🎯Target Audience
Target Audience Application Scenarios
Climbing Enthusiasts Leading climbers, top rope protection, double rope rappelling
Ice climbers: Excellent low-temperature performance for ice wall climbing
Rope rescuers: Precise control of descent speed
High-altitude workers: Durable backup descender
Cavite explorers: Strong corrosion resistance in wet and muddy environments
💡Why choose stainless steel ATC?
If you:
Frequently work in wet, muddy environments near the sea
Need a durable descender that doesn't require frequent replacements
Prefer the feel and solidity of metal equipment
Hope a descender can last for years or even be passed down through generations
