The invention relates to extrusion dies. It relates to a die comprising two interacting members 1, 8. The first member 1 has flared openings 2 which traverse it and which are arranged symmetrically with respect to a mandrel part 5. The latter interacts with a groove of the second member to delimit an extrusion space 21. It is advantageous for the second member to include an attached ceramic element intended to reduce wear during extrusion. Application to the extrusion of hard materials, such as copper. <IMAGE>
