Copper is preferable to aluminum and the size of wire should be the same or the next size down if copper is used.
Aluminum and Copper Wire
Aluminium wire has high resistance than Copper.

Yes, you can use an aluminum wire. Aluminum does conduct electricity. However, there is a well-known problem with aluminum wire. When exposed to air, the outer layer of aluminum forms a non-conductive oxide. There is resistance to the flow of electricity as it attempts to get through the aluminum oxide coating to the conductive aluminum below. When aluminum wire is used to reduce weight, it is usually welded to another metal that makes a better contact, such as copper. The contact metal is then what is connected.
If I were facing this issue, I would run a new copper wire for the range circuit. Call an electrician, who can provide you with options.
No, do not mix aluminum wire with copper wire.
In the electrical trade aluminum wire is equivalent to copper wire as it is also used to carry current. To carry the same current as copper wire aluminum wire is up sized to meet the same ampacity.
Aluminum and Copper Wire
Aluminium wire has high resistance than Copper.
When compared by volume, copper is best, then aluminum and finally iron. When compared by weight, aluminum is better than copper. You have to compare by volume because aluminum is so much lighter than copper, an aluminum wire that weighed the same as a copper wire would be much bigger and harder to work with.

A rather thin copper or aluminum wire.
Standard Romex is a three-strand, solid core wire, individually insulated, in a common sheath to make it easier to pull. For a short time, some manufacturers were making romex with aluminum because the cost of copper was so high, but the aluminum wire was not as good as the copper, and the practice was discontinued.
Place a piece of aluminum wire into a copper sulphate solution. Aluminum will replace the copper in the copper sulphate and copper will come out of solution and form along the aluminum wire, actually replacing the atoms of aluminum. The chemical equation is 2Al(s) + 3CuSO4(aq) ---> 3Cu(s) + Al2(SO4)3(aq). This kind of reaction is called a single replacement or single displacement.
