Nonferrous metals are rarer and as a result more expensive, but they have many properties that ferrous metals do not. Metals such as aluminum and titanium have a higher strength to density ratio than steel. Copper and silver are often used for their high conductivity and zinc is resistant to corrosion. Silver is also known for its reflectivity and malleability.
Polymers like nylon and acetal have good fatigue resistance. Plastics are light and very easily moulded with an excellent finish. Whatever material your project requires, there is a better than good chance we have worked with it before.
