you ask for long lasting that would be tungsten carbide but i suggest using easy to manufacture, easy to find, low cost because it will wear anyway so copper, with little lead ( often copper sold will be 'machineable' which means lead which means higher wear ) for a key way you should be able to

Know a little bit about welding. Have seen manufacturer of welding equipment claiming adding some welding on new parts used for digging might be good since weld is harder and wear slower. I am however certain welding is a lot more expensive material than buying a solid block and are in doubt ab
