Materials of genuine quality would not get contaminated or eroded easily.

Just like that people of sterling character would not get affected seriously by the company they keep..

The subhashitam quoted above deals with exceptionally great and noble people.

The meaning is --

The noble and virtuous people do not veer towards evil tendencies even if they are in the company of people with evil propensities. A venomous serpent may coil around the trunk of a sandalwood tree. But the Sandal extract would never get poisonous.
