1, stability
Black walnut volume shrinkage rate of 10.2% in North America, second only to the soft cherry, with a very rare hardwood stability, not easy in the humidity changes in cracking, deformation.
Teak structure in the coarse fiber, medium weight, dry shrinkage coefficient is very small, is the smallest deformation coefficient of wood in a kind of bending resistance, extremely wear-resistant, in the sun, rain, dry and wet changes in the case of not warping not cracked, expansion and contraction of all the wood is the smallest.
So on the stability of wood, teak is better than black walnut.
2, waterproof
Teak is the only seawater erosion and sun exposure does not occur under the bending and cracking of the wood, teak over the centuries by the seafarer is considered the world's most durable wood. It is widely used for yachts, bridges and other buildings. Burmese teak, which is more than 50 years old, has a very high oil content and absorbs little water even when soaked in water. This is why teak can be used as a shower floor or bathroom floor. It is also one of the reasons why shipbuilders choose teak as a material for shipbuilding.
So in terms of water resistance, Burmese teak is superior to black walnut.
3, visual effect
