The Bonsai Aluminium Wire 4.0mm is black anodised aluminium wire in a 100 g roll, for temporary branch training and for securing a tree during repotting. Aluminium is easier to work than copper, but correct gauge selection and frequent checking remain essential.
A secure anchor and even coils distribute holding force along the branch.
Flexible aluminium needs less application force than copper and supports gradual adjustments.
The dark anodised surface reduces the visual prominence of wire on trunk and branches.
Suitable for temporary branch guidance and careful securing in a pot.
This gauge can be considered initially for stronger primary branches or selected trunk work. It is not a guarantee of suitability without testing.
Choose a length that allows a secure anchor and covers the route without a join midway.
Pass the wire through suitable holes and secure it without creating a pressure point on roots or trunk.
The branch keeps position without multiple wraps.
Use small movements and finger support.
Change diameter instead of adding force.
The 4.0 mm may suit stronger primary branches or selected trunk work, but the rule is only a starting point. Test a short length in a safe area first.
The wire supports the new position without multiple layers and without compressing the bark.
Wire that is too thin will not hold; wire that is too thick increases the risk of damage during application.
Wood stiffness and bending direction vary by tree. Old or brittle wood requires particular care.
Always support the branch with your fingers close to the work area and do not press the wire into the bark.
Begin from a stable point so the wire does not shift when bending starts.
Keep the coils even, without overlaps and without trapping leaves or buds.
Support the branch and use small, controlled movements rather than one abrupt bend.
When removal is due, cut the wire at every turn; do not unwind it from the branch.
Check often, especially during strong growth. There is no single fixed interval that suits every species and season.
Diameter, net weight, material and finish for this specific pack.
Nominal gauge of this specific product.
One roll of wire.
Flexible for hand application with the correct tool.
Dark finish for a more discreet appearance on the tree.
Used to hold a new position temporarily while the branch adapts.
It can pass through suitable pot holes for stabilisation without pressing on the trunk or roots.
Cut ends can be sharp. Use a suitable wire cutter and keep the remaining roll organised.
Keep the loose end controlled while cutting.
Cutting each coil reduces friction and the risk of bark damage.
Wire and cutters are not toys.
Black anodised aluminium bonsai wire.
Tools and display items are sold separately.
Cover drainage holes before passing separate securing wire so the substrate is retained without blocking water flow.
As a starting test, use wire with a diameter around one third of the branch diameter. Wood stiffness and flexibility affect the result, so test a short length first.
At about 45°, with even coils and no overlap. The wire should make stable contact without pressing into the bark.
Before it begins to mark the bark. Check regularly and more often during strong growth because timing varies by species and season.
For safe removal from a branch, cut the wire at every coil rather than unwinding it. The cut sections should not be reused for new branch training.
Yes, when passed through suitable holes and positioned to stabilise the tree without damaging the trunk or roots.
No. The package contains only one 100 g roll of wire in the stated gauge.
