Diecast
Nearly all Dinky Toys were diecast, although a few early models and some accessories were made of tinplate or had tinplate parts to them. A mould would be created in the shape of the model then Mazak, a zinc based alloy, was poured in.

The composition of the Mazak in early models proved to be inferior and many of these crumbled with age. Today these models are extremely rare and good examples fetch high prices.
