Ipe
Tabebuia species

Also known as: Amapa, Cortez, Guayacan Polvillo, Flor Amarillo, Greenhart, Lapacho Negro, Madera Negra, Tahuari

Origin: Brazil and throughout continental tropical America as well as in parts of the Lesser Antilles.

Appearance:

The heartwood of ipe ranges from olive brown to blackish, though it can have lighter or darker striping that is sharply demarcated from the whitish or yellowish sapwood. Ipe is a low-luster wood with an oily appearance, a fine-to-medium texture, and a grain that ranges from straight to very irregular.

Resistance, Durability:

Along with its extreme hardness, strength, weight, density, and durability, ipe is also one of the most stable woods available. However, it is important to "over-dry" the wood in a kiln to avoid excessive shrinkage when installing.

Janka Hardness: 3684

As a flooring choice, ipe is an incredibly hard and durable wood species. It is over ninety-one percent harder than merbau, is roughly one hundred and twenty-six percent harder than wenge, and over two thirds harder than santos mahogany's ranking of 2200.

Workability:

Ipe is moderately difficult to work, given its hardness, especially with hand tools, and it has a blunting effect on most cutting edges. Pre-drilling is required when nailing the wood.

Main Uses:

Ipe is ideal for wood flooring where durability and high shock resistance are needed, such as in industrial environments. It is also used in railroad crossties, heavy construction, tool handles, and decorative veneers.

What is a Janka Rating?

"It is one of the best measures of the ability of a wood species to withstand denting and wear. It is also a good indicator of how hard a species is to saw or nail.

The hardness of wood usually varies with the direction of the wood grain.

A common use of Janka hardness ratings is to determine whether a species is suitable for use as flooring."

Colored Bamboo

Some species have different janka ratings depending on how they have been treated.

Bamboo is one example of this. If left with a natural finish, Bamboo falls at 1380 on the hardness scale. If you carbonize it to get a darker color, the rank falls to 1180.
