Top Trusted Timascus Pen Blanks Factories & Exporters serving El Salvador

Our standard off-the-shelf Timascus pen blanks are supplied in cylindrical rods with diameters of 12.7 mm (1/2"), 14.5 mm, 16.0 mm, 18.0 mm, and 20.0 mm, typically pre-cut to lengths of 125 mm to 150 mm (ideal for single-piece or two-piece fountain and rollerball pens). We also supply square billets (e.g., 20x20x150 mm) for custom CNC milling and centerless ground precision rods for automatic bar feeders. Custom diameters and specific multi-layer pattern densities can be configured to customer specifications with low minimum orders.

Because Timascus combines Grade 2 CP Titanium with Grade 5 (Ti-6Al-4V), both alloys oxidize at different voltage thresholds and temperatures. After turning and polishing the blank up to 2000-grit (or mirror buffing):

Thermal Anodizing (Torch Method): Gently apply a clean propane or butane flame while rotating the workpiece slowly. The Grade 5 layers will shift through bronze, purple, royal blue, and golden green, while the Grade 2 layers yield contrasting silver, pale blue, or golden straw tones.

Electrochemical Anodizing: Submerge in an electrolyte bath (e.g., baking soda or TSP solution) using a variable DC power supply (0–120V). Controlling voltage allows exact repeat color spectrums without degrading surface hardness.

Titanium exhibits low thermal conductivity ($k \approx 6.7 \text{ W/m}\cdot\text{K}$), meaning heat concentrates directly at the cutting tip rather than dissipating into the chips. We recommend:
• Tooling: Use sharp, positive-rake uncoated carbide inserts (ISO grade K10–K20) or polished PVD TiAlN-coated micrograin inserts designed for aerospace alloys.
• Cutting Speeds: Maintain surface speeds between 80 and 130 SFM (approx. 25–40 m/min). Keep feed rates positive (0.05–0.12 mm/rev) to stay beneath the work-hardened layer.
• Coolant: Generous flood coolant or high-pressure micro-lubrication (MQL) is essential to avoid thermal build-up and prevent tool galling.

Shipments destined for El Salvador (entering via San Salvador SAL Airport or the Port of Acajutla) are categorized under the Central American Tariff System (SAC). Timascus pen blanks and raw titanium rods fall under SAC Heading 8108.90 (Titanium and articles thereof, including waste and scrap) or SAC 9608.99 (Parts of pens) depending on finished state. Velnora supplies full commercial documentation, including verified Commercial Invoices, Packing Lists, airway bills, and Mill Test Certificates to ensure straightforward clearance through the Salvadoran Customs Authority (Dirección General de Aduanas - DGA).

For standard stocked Timascus rods and pen blanks, our minimum order quantity starts as low as 1 to 5 pieces for sample verification and prototype turning. Standard bulk production batches range from 20 to 100 units. Express air door-to-door delivery (DHL Express / FedEx Priority / UPS) to San Salvador or Santa Tecla takes approximately 4 to 7 business days. Larger sea freight shipments bound for Acajutla typically take 25 to 35 days.

Our proprietary vacuum diffusion bonding guarantees full metallurgical fusion, eliminating structural delamination under normal drilling conditions. However, when drilling deep holes (e.g., 7 mm or 10 mm internal diameters along a 130 mm blank), turners must use parabolic flute drills or cobalt split-point bits, peck frequently to evacuate chips, and ensure continuous coolant flow. Never let the drill dwell inside the hole, as titanium work-hardens rapidly if rubbing occurs.
