Product Description

Product Description

 

Rare earth neodymium magnetic hooks use neodymium magnets to attract on the flat surface and the hooks to hang the objects. They are well suited for carpentry, metal kitchen utensils, exhibition stand construction, shopfitting, signage technology, etc. The cup shaped metal shells are designed to optimize the magnetic flux to make the pull force bigger. The standard magnet material is NdFeB N35 and standard surface treatment is nickel plating both for the magnet and metal shell.

Remarks:
1. The SST results differ from coating. In general, Salt Spray Test result for the magnets with barrel plating (normally for small size of magnets), is better than the ones with rack plating (normally for big size of magnets).
2. Salt Spray Test (SST) condition: 5% NaCl, 35°C, continuously spray a certain time, test whether there is corrosion on plating/coating surface.
3. Pressure Cooking Test (PCT) condition: 2 atm, 95% RH (Relative Humidity), 121°C to test the plating/coating adhesion. (Zinc, Passivated/Phosphated, and Epoxy not suitable for PCT).
4. Other test methods for plating/coating: Drop Test, Cross Cut Test, Heating and Spilling Test, Constant Temperature, Humidity Test, etc.
