AINiCo is composed primarily of Aluminum Nickel Cobalt and also Copper and Titanium. They are manufactured through either casting or sintering process. Cast AINiCo may be manufactured in complex shapes such as horseshoes not possible with other magnet materials. Sintered AINiCo offer slightly lower magnetic properties but better mechanical characteristics. it can be efficiently magnetized in any direction, and for anisotropic AINiComagnet, it generally has greater magnetic capacitive in a preferred orientation than isotropic types. AINiCo is hard and brittle, Machining or drilling cannot therefore be accomplished by ordinary methods. Holes are usually cored in at the foundry, and magnets are cast close to final size and then finish machined to closer tolerances.

â?¢ Advantages of AlNiCo Magnet:
1.Customized designs are available.
2.Max working temperature can be as high as 550�°C.
3.Disadvantage: Br and BH(max)are not as high as rare earth magnet.
4.High energies and relatively low coercivity.
5.High magnetic flux density; low mold charge stable temperature properties; easy to shap.

Why not use a Carbon based Gas Diffusion Layer in an Electrolyzer
Carbon based GDL materials will be consumed and converted into CO2 gas in the presence of the Oxygen ions and Voltage found on the Anode (Oxygen) side of the electrolyzer. This secondary reaction of oxidizing the Carbon in the GDL will give temporarily lower electrolysis voltage, but this is a short lived phenomenon. The carbon GDL is quickly consumed, resulting in poor compression in the stack, and thus high resistance and lower performance.
You can still used carbon cloth or carbon paper material on the Hydrogen side (cathode) since there is oxygen on that side that will oxidize the GDL material.
