Cow magnets are popular with dairy farmers and veterinarians to help prevent hardware disease in their cattle. While grazing, cows eat everything from grass. And dirt to nails, staples and bits of bailing wire (referred to as tramp iron).

Tramp iron tends to lodge in the honeycombed walls of the reticulum, threatening the surrounding vital organs and causing irritation and inflammation, known as hardware Disease. The cow loses her appetite and decreases her milk output (dairy cows), or her ability to gain weight (feeder stock). Cow magnets help prevent this disease by attracting stray metal from the folds and crevices of the rumen and reticulum.

One magnet works for the life of the cow. These cow magnets also make a great addition to your science project. They are very powerful and are great for general experimentation with magnets. There are several kinds of cow magnets:

1) Ceramic cow magnet: This rectangular cow magnet is made of ceramic 5 (Strontium Ferrite) magnet material. Its special magnetization pattern causes nails and other sharp metal objects line up along the length of the magnet where they are no longer a danger to the cow. The FDA-approved epoxy coating is gentle on the cow and helps protect the magnet from chipping. Rounded corners ensure safe and easy passage to the reticulum.

2) AlNiCo 5 cow magnet: A favorite of dairymen and vets for over 30 years. This is the standard cast AlNiCo cow magnet with bright, metal finish. It is non-toxic and non-corrosive in use.

Testing Center

We are ISO/TS16949:2002 certified and well implement all procedures strictly under control. Problem preventive actions and quality assurance are preoperly combined with special inspection for all procedures from raw material purchasing ,outside cooperating part manufacturing,inside manufacturing to shipping . We also install a complete set of physical and chemical test equipment to make sure that all our products are manufactured and shipped under strictly quality control .

Salt Spray Test :

Mainly test the surface treatment against the corrosion.  Usually the tested samples will be  continuous sprayed 24 hours in the 35℃ temperature to see if there is any rust appearance on the surface. 

Projection Instrument:

Mainly test the magnets with irregular shapes such as arc segments and any other irregular-shaped parts to see if their dimensions meet the customers' requirements or not.  

PCT Instrument:

Mainly test the magnets to prevent against corrosion on the high temperature and high atmospheric pressure . Usually the test condition is 120℃ temperature and 2 atmospheric pressure .

Heat& Humidity Instrument:

Mainly test the magnet to against corrosion on certain temperature and humidity . Usually the test condition is 80℃ temperature and 90%+/-3% humidity

Hysteresgraph:

Mainly test the magnetic characteristics of the magnet, including Residual (Br ), Coercive(Hcb) . Intrinsic  Coercive(Hcj), Max. Energy product(BH max) and any other related magnetic parameters.
