In the United States, it is distributed in Iowa, Maine, Michigan, Minnesota, North Carolina, New Hampshire, New Jersey, New York, Ohio, Great Smoky Mountain National Park, Maryland, Massachusetts, Connecticut, Kentucky, Illinois, Pennsylvania, South Carolina, Tennessee, Virginia, Vermont, Wisconsin, West Virginia, and Indiana. usually found growing in pure stands, and is adapted to swamps and neutral alkaline soils on limestone uplands. Heartwood Color Brown Green/grey Pink Pale brown Yellow to golden-yellow to orange White to cream Straw brown Brown Often has numerous small knots Sapwood Color Brown White to yellow Paler than heartwood Narrow Grain Straight Even Figure Growth rings (figure) Straight Figure shows rays Even Clear growth rings (figure) The wood is typically straight and even grained, and growth rings are not prominent Texture Medium Coarse Fine Even textured Luster Medium Natural Durability Perishable Durable Resistant to attack from powder post (Lyctid & Bostrychid) beetles Very durable Heartwood has high natural resistance to decay Heartwood is highly suitable for use in applications where it is exposed to high decay hazard conditions such as shingles, boats, greenhouses, outdoor furniture, and log pilings. Northern white cedar is reported to acquire a silvery sheen, with fine and indistinct surface checks after prolonged exposure to the weather. Odor Has a characteristic cedary smell and a faint bitter taste Toxicity Dermatitic effects Kiln Schedules T12 - B4 (4/4); T11 - B3 (8/4) US/T12 - B4 (4/4); T11 - B3 (8/4) US Drying Defects Checking Distortion Ease of Drying Fairly Easy Variable Easy Dries well with very little shrinkage and degrade Tree Identification Bole/stem form is buttressed Bole/stem form is fluted Tree Size Tree height is 20-30 m This is a slow growing tree, which may reach 400 or more years of age Boring Fair to good results Fairly easy to very easy Easy Carving Fair to Good Results Fairly Easy to Very Easy Cutting Resistance Easy to saw Gluing Very good properties Easy to glue Mortising Fair to Good Results Fairly Easy to Very Easy Finishes well Easy to mortise Moulding Fair to Good Results Fairly Easy to Very Easy Good finishing results Easy to mould Movement in Service Stable Stable when seasoned Small Nailing Fair to Good Results Very Good to Excellent Results Fairly Easy to Very Easy Nails hold poorly Planing Fair to Good Results Fairly Easy to Very Easy Planes well, to a good finish Easy to plane Resistance to Impregnation Resistant sapwood Resistant heartwood Heartwood is resistant Sapwood is permeable Poor response to preservative treatment Heartwood is extremely resistant Response to Hand Tools Responds Readily Easy to machine Yields a smooth, clean finish Responds well to ordinary machine tools in most operations Routing & Recessing Fair to Good Results Fairly Easy to Very Easy Routing yields good results Routing is easy Sanding Fair to Good Results Fairly Easy to Very Easy Screwing Fair to Good Results Very Good to Excellent Results Fairly Easy to Very Easy Poor screw holding properties Poor results Turning Fair to Good Results Fairly Easy to Very Easy Good results Easy to turn Steam Bending Fair to Good Results Poor The timber has poor steam bending qualities, with a large proportion of broken pieces Painting Good results Very good painting qualities Staining Fair to Good Results Very Good to Excellent Results Stains well Finish is generally good Varnishing Fair to Good Results Fairly Easy to Very Easy Strength Properties Density (dry weight) = 15-22 lbs/cu. ft. Work to Maximum Load = very low Shearing strength (parallel to grain) = very low Modulus of Elasticity (stiffness) = very low Max. crushing strength = low Hardness (side grain) = very soft Density (dry weight) = 23-30 lbs/cu. ft. Bending strength (MOR) = very low Toughness-Hammer drop (Impact Strength) = very low Soft Shrinkage, Tangential = very small Shrinkage, Radial = very small Dents or scratches easily Density (dry weight) = 31-37 lbs/cu. ft. Bending strength (MOR) = low Northern white cedar has low strength properties in stiffness, hardness, and resistance to shock Numerical Data Item Green Dry English Bending Strength 3380 5098 psi Crushing Strength 225 304 psi Density 22 lbs/ft3 Hardness 322 lbs Impact Strength 15 13 inches Maximum Crushing Strength 2086 3978 psi Shearing Strength 875 psi Stiffness 839 1011 1000 psi Work to Maximum Load 5 5 inch-lbs/in3 Specific Gravity 0.28 0.29 Weight 23 22 lbs/ft3 Radial Shrinkage 2 % Tangential Shrinkage 4 % Volumetric Shrinkage 7 % Item Green Dry Metric Bending Strength 237 358 kg/cm2 Crushing Strength 15 21 kg/cm2 Density 352 kg/m3 Hardness 146 kg Impact Strength 38 32 cm Maximum Crushing Strength 146 279 kg/cm2 Shearing Strength 61 kg/cm2 Stiffness 58 71 1000 kg/cm2 Work to Maximum Load 0.35 0.35 cm-kg/cm3 Specific Gravity 0.28 0.29 Weight 368 352 kg/m3 Radial Shrinkage 2 % Tangential Shrinkage 4 % References Betts, H.S.,1949,American Woods - Northern White Cedar,USDA, Forest Service American Woods Bolza, E.,1976,Timber and Health,Div.
