Using phosphoric acid on aluminum is not sufficient, what is required is know how and one of Vanchem’s specific products. Vanchem has a unique product for aluminum castings VANCLEAN ALDC, which cleans, deoxidizes, and iron phosphates all in one-step. This cannot happen if one is using only phosphoric acid on aluminum.

Synopsis. AlPO 4 and GaPO 4 are formed in the reaction of phosphoric acid triesters OP(OR) 3 (R = Me, Et, n-Bu, SiMe 3) with aluminium and gallium amides [M(NMe 2) 3] 2 (M = Al (1), Ga (2)), respectively, in nonaqueous solvents.The model for the initial step in these reactions is an adduct (Me 2 N) 3 Al·OPPh 3 (3).AlPO 4 also results from the reaction of AlCl 3 with OP(OSiMe 3) 3.
Phosphoric acid (also known as orthophosphoric acid or phosphoric(V) acid) is a weak acid with the chemical formula H 3 P O 4. Orthophosphoric acid refers to phosphoric acid, which is the IUPAC name for this compound. The prefix ortho-is used to distinguish the acid from related phosphoric acids, called polyphosphoric acids.

PHOSPHORIC ACID reacts exothermically with bases. May react with active metals, including such structural metals as aluminum and iron, to release hydrogen, a flammable gas. Can initiate the polymerization of certain classes of organic compounds. Reacts with cyanide compounds to release gaseous hydrogen cyanide.
A typical preparation of an aluminophosphate involves the hydrothermal reaction of phosphoric acid and aluminium in the form of hydroxide, an aluminium salt such as aluminium nitrate salt or alkoxide under controlled pH in the presence of organic amines.
As ASparky said, phosphoric acid shouldn't do too much damage to aluminum. If it was pure, metallic aluminum it would only react with the surface and the rest of the material would be protected by a layer of aluminum phosphates- assuming it is pure orthophosphoric acid and the aluminum were pure aluminum.
