Integral colour anodising of aluminium is carried out by the constant voltage process using alternating current (A.C.) in an electrolyte containing 40 gll sulphosalicylic acid and 40 mlll formic acid in conjunction with 510 gll pyrogallol, pyrocatechol, p-aminophenol and metol at 2530°C with operating voltage between 50 and 80 V. Colours ranging from brownish black, yellowish green, brown, reddish brown, purple, chocolate and black are obtained. The colour depends on the composition of the alloy and operating conditions.
