1. A casting method of producing a wear resistant mining casting material, said method comprising:
(1) selecting an Fe alloy metal and a spinel ceramic each having a Coefficient of Thermal Expansion (CTE), a wetting contact angle (WCA), or a combination thereof;
wherein the Fe alloy metal has a CTE of from about 10 ppm° C.−1 to about 21 ppm° C.−1 and the spinel ceramic has a CTE of from about 6 ppm° C.−1 to about 11 ppm° C.−1; and
wherein the Fe alloy metal and the spinel ceramic have a WCA of <90°;
(2) manufacturing by an infiltration process a child metal insert casting comprising the compatible Fe alloy metal and the spinel ceramic; and
(3) placing the resultant child insert casting into a mother holding casting for specific design and locations using mechanical fixing chaplets before final Fe alloy metal pouring and solidification of a product.
