Ash Products

Ash (Fraxinus spp.)

Tilo makes a number of products using ash hardwood, including
  • architectural millwork and moulding
  • doors
  • flooring
  • furniture
  • kitchen cabinets
  • paneling
  • turnings

General Description of Ash

Sapwood of ash is light-colored to nearly white while heartwood varies from grayish or light brown to pale yellow streaked with brown. Wood is generally straight-grained with a coarse uniform texture.

Relative Abundance & Availability of Ash

4.6 percent of total U.S. hardwoods commercially available. Ash lumber is readily available.

Working Properties of Ash

  • machines well
  • good in nailing, screwing and gluing
  • can be stained to a very good finish
  • dries fairly easily with minimal degrade
  • little movement in performance

Physical Properties of Ash

Ash has very good overall strength properties relative to its weight. Excellent shock resistance and good for steam bending.

Strength And Mechanical Properties (inch-pound) (a)
Moisture content 12%
Specific Gravity (b)
Static Bending Modulus of Rupture (lbf/in2)
Static Bending Modulus of Elasticity (c) (106 lbf/in2) 1.04-1.74
Static Bending Work to Maximum Load (in-lbf/in3) 11.8-16.6
Impact Bending to Grain (in) 43
Compression Parallel to Grain (lbf/in2) 2,300-7,410
Compression Perpendicular to Grain (lbf/in2)350-1,420
Shear Parallel to Grain (lbf/in2)860-2,030
Tension Perpendicular to Grain (lbf/in2)940
Side Hardness (lbf)1,320

a) Results of tests on small clear specimens in the green and air-dried conditions. Definition of properties; impact bending is height of drop that causes complete failure, using 0.71-kg (50 lb.) hammer; compression parallel to grain is also called maximum crushing strength; compression perpendicular to grain is fiber stress at proportional limit; shear is maximum shearing strength; tension is maximum tensile strength; and side hardness is hardness measured when load is perpendicular to grain.

b) Specific gravity is based on weight when oven dry and volume when green or at 12% moisture content

c) Modulus of elasticity measured from a simply supported, center-loaded beam, on a span depth ratio of 14/1. To correct for shear reflection, the modulus can be increased by 10%.
