High quality U-shape Alnico concave magnets

1.Alnico description:

Alnico is the earliest development of permanent magnet materials, is made of aluminum, nickel, cobalt, iron and other trace metal elements of the alloy. According to production process can be divided into cast AlNiCo and sintered AlNiCo.

3.Characteristics of AlNiCo:

1,The highest working temperature can reach 550 degrees Celsius.

2, Strong corrosion resistance and oxidation resistance, product surface usually don't need plating processing.

3, The characteristics of low coercivity, in use process strictly prohibited it with any ferromagnetism content contact, lest cause local irreversible demagnetization or magnetic pass density distribution of distortion.

4, By adjusting the formula and processing method, can be processed into various shapes and sizes to meet the specific needs of customers.

4.Application of Alnico magnet:

Motor, sensor, meter, sound device, magnetic separator, automobile, aviation, aerospace and other applications

Packaging & Shipping

1. By Sea: As the magnets have strong attraction and we will use the spacer to apart the magnets each other in case people will be hurt when take it out. Then, they will be packed in a white box of pieces each, several boxes to a carton. (Detailed package quantity should be made upon the real products)

2. By Air: If the goods will be shipped by air, all the magnetic should be degaussed and we will use Iron sheet to shield.

Shipping: Express (TNT, DHL, FedEx, UPS, etc), Air, Ocean.
a: The weight is under 40Kgs, we recommend to send them in shielding boxes to you by Express.
b: The weight is between 40Kgs-100Kgs, it can be sent by Express or Air.
c: The weight is over 100Kgs, we recommend to send them by Ocean.
