Drilled Titanium Clad Copper Flat Bar

Drilled Titanium Clad Copper Flat Baris a precision machined composite flat bar combining a high conductivity copper core with a corrosion resistant titanium outer layer. Drilled holes can be incorporated into the flat bar according to specific mounting, connection, or equipment requirements.

The flat bar design provides a larger contact surface and convenient installation, while the titanium cladding protects the copper core in demanding operating environments.

Ti-Cu Clad Flat Bar with Holes is a composite material made by bonding pure titanium (Grade 1 or Grade 2) and high conductivity copper (C11000/C10200) through explosive welding or hot rolling. On this clad bar, precision drilling or CNC machining is applied to create straight holes, deep holes, countersunk holes, or custom hole patterns, enabling direct installation in electrochemical equipment and power distribution systems.

We manufacture custom drilled titanium clad copper flat bars according to customer drawings, samples, or technical specifications. Bar width, thickness, length, titanium cladding thickness, hole diameter, hole spacing, and hole layout can all be customized.

Customized Drilling & CNC Machining

We provide:

· Through hole drilling

· Deep drilling

· Countersunk holes

· Slot holes

· Threaded holes

· Multi-hole patterns for electrical installation

Excellent Corrosion Resistance + High Conductivity

Titanium (Ti) layer protects against acid, alkali, chlorine, seawater, electrolysis environments

Copper ensures excellent electrical and thermal conductivity

Lightweight + Cost Effective

A Ti-Cu clad bar offers titanium corrosion resistance at 1/3 the cost of solid titanium bars.

The drilled design allows the flat bar to be supplied as a finished component rather than requiring additional hole machining after delivery.

Depending on the drawing, we can manufacture:

· Through holes

· Blind holes

· Threaded holes

· Counterbored holes

· Countersunk holes

· Single holes

· Multiple-hole patterns

· Regular or irregular hole layouts

Hole diameter, center distance, edge distance, depth, and positional tolerances can be controlled according to the customer's specifications.

For projects using the term Titanium Clad Copper Perforated Bar, we can also manufacture perforated or multi-hole configurations based on the required layout.

A typical production route includes:

Copper & Titanium Preparation → Surface Preparation → Cladding/Bonding → Sizing → Cutting → Flat Bar Machining → Drilling → Edge & Surface Finishing → Inspection → Packaging

The actual manufacturing process is selected according to the composite structure, dimensions, cladding requirements, hole configuration, and specified tolerances.

A titanium clad copper flat bar is designed to combine the advantages of two materials in one component.

Copper core provides high electrical conductivity.

Titanium cladding provides a corrosion-resistant working surface.

Flat-bar geometry offers a broad contact area and convenient mounting.

Precision drilling allows holes and connection features to be integrated into the finished component.

This composite design can be advantageous where a conventional copper flat bar may have insufficient corrosion resistance and solid titanium may not provide the required electrical conductivity.
