Composite tooth and manufacturing method thereof

The invention discloses a composite tooth and a manufacturing method thereof. The composite tooth comprises a tooth core part and a core wrapping part; the tooth core part is sleeved with the core wrapping part; the first end of the tooth core part and the first end of the core wrapping part are located on the same plane or the first end of the tooth core part protrudes out of the first end of the core wrapping part; and the toughness of the core wrapping part is larger than that of the tooth core part. The manufacturing method comprises the steps that the tooth core part and the core wrapping part of the composite tooth are connected through interference fit or welding; a tail section part is vertically placed, the end face, connected with the tooth core part, of the tail section part is coated with brazing flux, and a brazing filler metal soldering lug, a metal net and the tooth core part are sequentially placed; the brazing flux and the brazing filler metal soldering lug are heated to be melted, and heatin
