YueFong Padlock Comparison
What separates a genuine YueFong padlock from a lower-cost comparison sample?This engineering comparison examinesmaterial mass,internal construction,mechanical strengthandcorrosion resistanceusing recorded laboratory test data.

Engineering Below the Surface
The most important differences are not always visible from the outside. Material quantity, internal architecture and component selection directly influence mechanical durability and long-term performance.
147 g vs 92.5 g
The YueFong sample measured 147 g, compared with 92.5 g for the comparison sample.Weight alone does not define security, but when combined with a robust metal structure, greater material mass can contribute to improved resistance to impact, deformation and mechanical fatigue.


What You Cannot See Matters
Internal construction reveals differences that are hidden during a normal external inspection.The YueFong sample uses metal alloy components in its internal structure, designed to provide mechanical stability, precision and durability.The comparison sample contains plastic components in internal areas, reducing the amount of metal used in the core assembly.


Destructive Tensile Testing
Samples were subjected to mechanical testing to compare their behavior under high-load conditions.

| Test | Reference | YueFong Result | Comparison Sample |
|---|---|---|---|
| Tensile Test 50 mm combination padlock | ≥ 2500 N | 2595 N Recorded result | 258 N Lower recorded result |
| Cutting Test | Internal test parameters | 15,000 N Recorded value | 17,000 N Evaluated against applied criteria |
240-Hour Salt Spray Test
Corrosion directly affects the durability of metal hardware.The samples were tested under neutral salt spray conditions using a saline concentration of 5% ± 1% NaCl, a chamber temperature of 35°C ± 2°C, and a total exposure duration of 240 hours.

YueFong Padlock Comparison: Materials, Strength and Quality Control
A meaningful YueFong padlock comparison requires more than judging external appearance.Mechanical security depends on material selection, internal architecture, component precision, resistance to high loads and long-term corrosion protection.
In this comparison of the YueFong 50 mm combination padlock, the tested sample recorded a mass of 147 g and a tensile test result of 2595 N.Internal inspection also shows differences in the use of metal components compared with plastic components found in the comparison sample.
Environmental durability was evaluated through a 240-hour neutral salt spray test.Photographic records captured at multiple intervals provide a visual comparison of how the two samples changed during accelerated corrosion exposure.
