新西蘭大柏樹、大果柏 Macrocarpa

Cupressus Macrocarpa
Family : Cupressaceae
Country of Origin : United States of America
Wood Type : Softwood

Macrocarpas natural habitat is limited to the peninsular of Point Lobos,           near Monterey, in Southern California, also the home of Radiata Pine.           It was introduced to New Zealand in the 1860s and was planted mainly           as shelter belts but occasionally as plantations.

The timber is a low to medium density softwood (485 kg/m³ at 12%           moisture content) and has a large amount of heartwood which is a golden           brown honey colour. Macrocarpa is a moderately stiff, strong timber similar           to NZ grown Douglas Fir, it is a difficult timber to kiln dry with cell           collapse and internal checking the main problems.

Macrocarpa clears are very similar to Kauri in character, and machines           and turns well owing to its fine texture.

Macrocarpa is one of the most naturally durable exotic softwoods grown           in New Zealand, and is resistant to insect and borer attack in its sawn           form.

Its heartwood is rated           moderately durable which means a 50x50 stake will last 10-15 years in           the ground. Larger sections will last considerably longer. Outside and           above the ground macrocarpa is equivalent to H3 pine in durability. Inside           where the timber is not subject to the elements, it will last virtually           indefinitely.

Macrocarpa, when dry, will accept a variety of paints, oils, two pot           resins, and varnishes.
