Practical Powerful Rare Earth Metal Tools Salvage Neodymium Retrieval Fishing Magnets

Product Description

Product Details

Neodymium fishing magnets for ferrous metal salvage are used to salvage ferromagnetic metals under the water with a rope tied on the hanging rings. SM series fishing magnet has the model with top and sided eyebolts to reduce missing possibility under the water. They are also used as pot magnets 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.
