Leadkeels

Capacity:
Finn keels, wing keels, bulb keels, swing keels,- without limit in type, size or
weight, according to yacht yard, designer's and owner's drawings, to be
delivered worldwide at fixed and competitive prices.

Lead quality, alloys and properties:
Pure lead without antimonies alloy cannot be used for keels because of lack
of hardness and strength.
Where nothing else is specified ØRKILD makes keels from 99,5% of pure lead
with an antimonies alloy of 2% - 3%, which gives the lead a Brinell hardness
of app. 10 and a tensile strength of appx. 3,5 kgs. per.sq.mm., thus making
lead into a suitable material for keels.

Lead with 2% of antimonies alloy has specific weight 11,2. Where technical demands require even greater hardness or strength, lead can be poured
with higher antimonies alloy to suit the specific purpose. To ensure a homogeneous keel,
keels are poured horizontally where this is possible.

ØRKILD is only using pure and specified lead. Keels can be delivered with certificate.

Surface:
Lead keels are delivered with surfaces ground with 35- grit grinding sheaves, which
gives a slightly rough surface with good adhesive to the following surface treatment.

For specific racing or one-off boats ØRKILD is able to supply keels being
CNC-machined on surfaces.
