The micromixer includes a fuel plenum (124), an air plenum (126), and a plurality of mixing tubes (130). Certain mixing tube(s) (150) include a body portion (160) made of a first material and including a first end and a second end, the first end in fluid communication with the fuel and air plenums. A cladded tip portion (170) made of a second, different material is coupled to the second end of the body portion. The cladded tip portion includes a combustion end (172) configured to direct the fuel-air mixture into the combustion chamber. A tapered inner surface (180) extends from the combustion end of the cladded tip portion to a location (182) on the body portion. The body portion has a cylindrical inner diameter (ID1) from the location to the first end of the body portion.
