Product Description
Jovvi Non-Magnetic Titanium Tool Kit for MRI Engineering – Version 3 (Step‑by‑Step Selection Guide for MRI Engineers)
1. Quality – Understanding the Three Titanium Grades Used by Jovvi

Not all titanium tools perform the same. Jovvi selects specific titanium alloys based on tool function:

Titanium Grade Composition Hardness (HRC) Used For Key Property
Grade 2 (Commercially Pure) 99.2% Ti 20–25 Tweezers, rulers, putty knives Formability, corrosion resistance
Grade 5 (Ti‑6Al‑4V) 90% Ti, 6% Al, 4% V 36–42 Hex keys, screwdrivers, wrenches, sockets High strength, wear resistance
Grade 23 (Ti‑6Al‑4V ELI) Extra low interstitials 34–38 Torque wrenches, cryostat tools Fracture toughness at low temperature

Quality guarantee: Every tool is laser‑marked with grade code (e.g., “Gr5” for Grade 5). No mixing of lower grades without disclosure.

2. Application Scenarios – Task‑Based Selection Flowchart

Use the following decision tree to select the correct Jovvi tool for each MRI engineering task.

Step 1: Identify the MRI Zone and Field Strength
Zone Field Strength Tool Requirement Recommended Jovvi Kit
Zone IV (Scanner Room – within 0.5 m of bore) 0.5–7 T Maximum safety, no artifacts ProKit‑2 or ProKit‑3
Zone III (Control Room – outside 0.5 m but inside Faraday cage) < 0.5 mT Non‑magnetic, lower artifact concern ProKit‑1 (sufficient)
Zone II (Corridor – outside shielded room) Earth field only Any non‑ferrous ProKit‑1 or standard brass tools
Inside bore (during servicing with magnet ramped down) 0 T (if ramped) Any, but Jovvi Ti still recommended Any kit (magnetic susceptibility irrelevant when field is zero)

Jovvi note: Even when the magnet is ramped down, residual magnetism in steel tools can later transfer to scanner components. Always use titanium.

Step 2: Identify the Specific Task – Tool by Tool
Task Category A: Fastener Manipulation (Screws, Bolts, Nuts)
Fastener Type Common Location Recommended Jovvi Tool Titanium Grade Alternative (Not Recommended)
Hex socket (1.5–6 mm) RF coil covers, gradient panels Hex key set (L‑style) Grade 5 Brass hex keys (strip easily)
Hex socket (8–19 mm) Cryostat ports, patient table mounts Socket set + ratchet Grade 5 sockets + Be‑Cu ratchet 316 stainless (artifacts)
Torx (T6–T30) Magnet cover panels, RF screens Torx drivers (fixed handle) Grade 5 tip, brass handle Ceramic (brittle)
Phillips / Flathead Control console, accessory mounts Screwdrivers (3–6 mm) Grade 5 blade, brass/plastic handle 316 stainless (magnetizes over time)
Hex nut (exposed) Helium vent line flanges Open‑end wrench set Grade 5 Brass (jaws spread under torque)

Jovvi ProTip: For cryostat port nuts (often tight due to thermal cycling), use Jovvi torque wrench (1–10 N·m) with Grade 23 titanium socket. Never exceed 8 N·m on helium port nuts.

Task Category B: Cutting, Prying, and Striking
Task Recommended Jovvi Tool Titanium Content Safety Note
Cutting copper RF mesh Diagonal cutters 90% Ti jaws, bronze pivot Non‑sparking – safe near oxygen
Prying RF shield panels Titanium crowbar (300 mm) 100% Grade 5 Use plastic shims to avoid scratching copper
Removing old conductive paste Titanium putty knife 100% Grade 2 Flexible blade conforms to curved surfaces
Hammering copper fasteners Titanium hammer (200 g head) 100% Grade 5 Replaceable face inserts (nylon for soft blows)
Retrieving dropped screw inside bore Non‑magnetic pick‑up tool 100% Grade 5 stem, magnet‑free claw No magnet – uses mechanical grabber
Task Category C: Measurement and Inspection
Need Recommended Jovvi Tool Titanium Content Special Feature
Gap measurement (e.g., between RF coil and bore) Titanium ruler (150 mm or 300 mm) 100% Grade 2 Etched markings (no painted ink that could flake)
Depth measurement (socket head screws) Titanium depth gauge 100% Grade 5 Slide mechanism with brass lock screw
Visual inspection in tight spaces Non‑magnetic inspection mirror Titanium stem, acrylic mirror Mirror detachable for cleaning
Magnetic field detection (locating stray field) Not a tool – use gaussmeter N/A Never bring a gaussmeter inside bore – it will saturate
Step 3: Determine Kit Size Based on Frequency of Use
Usage Frequency Recommended Kit Rationale
Once per month (occasional service) ProKit‑1 (18 tools) Sufficient for 90% of fastener tasks
Once per week (in‑house MRI engineer) ProKit‑2 (32 tools) Adds sockets, ratchet, torque wrench, pliers
Daily (field service engineer, cryogen specialist) ProKit‑3 (45 tools) Adds deep sockets, crowbar, putty knife, inspection mirror
Department with >3 MRI scanners Two ProKit‑2 kits One kept in Zone IV, one in workshop – avoids cross‑zone contamination
