Tilmaamaha ugu muhiimsan ee kuleyliyaha garaafka:

1. isku mid ahaanshaha qaab dhismeedka kuleylka.

2. koronto wanaagsan iyo culeys koronto oo sarreeya.

3. iska caabin daxalka.

4. oksidizability.

5. nadiifinta kiimikada sare.

6. xoogga farsamada sare.

Faa'iidada waa tamar hufan, qiimo sare iyo dayactir hooseeya.Waxaan soo saari karnaa ka-hortagga oksaydhka iyo cimriga dheer ee garaafiga crucible, caaryada garaafka iyo dhammaan qaybaha kuleyliyaha garaafka.
